Alpha values, checkerboard transparency previews, and Display P3 color-space context stay visible before you copy.
SCREEN PICKER & FORMATS
Read the pixel you mean, then copy the value you need
A responsive magnifier, clear pixel grid, multi-display support, and retained sRGB or Display P3 context make sampling deliberate instead of approximate.
Picker made personal
Choose circular, rectangular, or rounded magnifiers in three sizes, six starting zoom levels, and four sampling qualities.
Color-space aware
Preserve sRGB and Display P3 information, with automatic foreground and target contrast over light or dark colors.
Copy with context
Preview the selected format, alpha percentage, transparency checkerboard, and P3 badge before copying.
A picker designed for real displays
The overlay follows the pointer across multi-display setups and keeps the current pixel readable at every zoom level.
Magnifier and grid
Inspect the live pixel grid with HEX and RGB visible at the same time.
Fast, reversible control
Click to complete a pick, press Esc to cancel, and use wheel or trackpad gestures to change magnification.
Adaptive contrast
Text and the target frame automatically switch for legibility over light and dark colors.
Color-space retention
Keep sRGB or Display P3 information with the sampled result.
Make the picker fit your work
Tune the overlay once, then keep those defaults for the next global pick.
Shape and size
Choose circle, rectangle, or rounded rectangle, plus small, medium, or large sizing.
Zoom and quality
Set one of six starting zoom levels and low, standard, high, or highest sampling quality.
Feedback controls
Enable or disable the pick sound and floating detail preview independently.
History behavior
Keep 20, 50, or 100 recent colors, or pause new history without deleting existing entries.
Copy without translating by hand
The selected output stays consistent across the picker, library, palettes, and analysis tools.
Simple and developer copy
Copy plain HEX instantly or use the currently selected development format.
Alpha-aware preview
See transparency on a checkerboard and retain alpha in formats that support it.
P3 visibility
Display a P3 badge when the sampled color carries Display P3 context.
Clear completion state
Receive immediate status feedback after a copy action.
PALETTE TOOLS
Turn one base color into a complete, explainable system
Build a ten-step scale, six saturation variants, and four practical schemes without losing the source color or its intended role.
10-step tonal matrix
Generate levels 50 through 900 with HEX values and role suggestions for backgrounds, dividers, text, and brand use.
Six tone variations
Keep the base hue while moving from softer low-saturation colors to stronger accents.
Four color schemes
Create complementary, analogous, triadic, and split-complementary combinations.
Ready for implementation
Copy a suggested variable name or open any generated color for all 22 output formats.
A tonal matrix with practical roles
The matrix turns a base color into a labeled light-to-dark system instead of an unstructured row of swatches.
Ten generated levels
Create 50, 100, 200, 300, 400, 500, 600, 700, 800, and 900 steps with HEX values.
Usage guidance
See suggestions for backgrounds, dividers, secondary text, brand color, and body text.
Source context
Review base-color HSB values and switch the source from recent or favorite colors.
Token-ready naming
Generate and copy a suggested variable name for implementation.
Tone variations for quieter or stronger emphasis
Six variants retain the base hue while changing saturation with an explicit background or accent recommendation.
Lower-saturation options
Generate softer colors that work more naturally across larger background areas.
Higher-saturation options
Find stronger candidates for controls, status, and emphasis.
Visible values
Every variation shows its HEX value without requiring another view.
Full detail on demand
Open any variation to preview it and copy a development format.
Four deliberate color relationships
The generator focuses on the four schemes available in the current product.
Complementary
Build direct contrast across the color wheel.
Analogous
Create neighboring colors with a more unified character.
Triadic
Balance three separated hues for a broader system.
Split complementary
Keep contrast while softening the opposition of a direct complement.
ACCESSIBILITY CHECKS
Evaluate readability before color reaches the interface
Compare text and background colors in real content, target the next WCAG level, and preview common color-vision simulations as a design aid.
Precise WCAG ratio
Check normal-text AA at 4.5:1 and AAA at 7:1 with the exact current ratio.
Practical content preview
Review a heading, body, and button rather than judging colors from numbers alone.
Smart optimization
Improve either text or background toward the next target while retaining hue and saturation where possible.
Color-vision preview
Compare normal vision with red-, green-, blue-, and complete color-vision deficiency simulations.
Build and inspect the color pair
Text and background stay independently editable and are saved for the next visit.
Flexible sources
Re-sample either role from the screen or select from recent and favorite colors.
One-click swap
Reverse text and background without rebuilding the pair.
Exact ratio
See the current WCAG contrast ratio and normal-text AA or AAA status in real time.
Live interface preview
Evaluate the pair across a heading, body copy, and button.
Improve the part you can change
When contrast is insufficient, Weeko Color proposes separate text and background adjustments.
Next useful target
Recommendations automatically aim for AA first, then AAA when AA already passes.
Before and after
Compare both colors and ratios before applying a suggestion.
Preserve character
Retain the original hue and saturation as far as the target allows.
Apply immediately
Update the active pair, ratio, and content preview with one action.
Preview color-vision differences
Simulation is a design preview, not a medical test or certification.
Five viewing modes
Compare normal vision, protanopia, deuteranopia, tritanopia, and achromatopsia simulations.
Simulate the full pair
Transform both text and background together to preserve their interaction.
Readability in context
Review the simulated content preview rather than isolated swatches.
Persistent selection
Return to the simulation mode used in the previous session.
LIBRARY & WORKFLOW
Keep useful colors close without sending them to a cloud
Recent picks, named favorites, global shortcuts, menu-bar access, and merge-safe JSON backups keep the library useful on a single Mac.
Recent and favorites
Deduplicate repeated picks, name and pin favorites, and clear either collection without affecting the other.
Menu-bar speed
Start picking, reopen any of the six latest colors, or jump to the matrix and contrast tools.
Conflict-aware shortcuts
Customize four global actions and see conflicts with other app actions or macOS shortcuts.
Merge-safe JSON backup
Validate imports, skip duplicates, migrate older backups, and preserve existing colors instead of overwriting them.
Recent colors and favorites stay distinct
Both collections share the same copy formats while retaining independent organization and clearing controls.
Useful recent history
New picks enter automatically; duplicates move to the front instead of creating another entry.
Named, pinned favorites
Promote a recent color, rename it, and pin important references above time-sorted favorites.
Direct actions
Click to copy, open color details, unfavorite, or delete a single recent item.
Independent clearing
Clear recent or favorites with a count and confirmation while preserving the other collection.
Reach the tools without interrupting your work
Weeko Color can act as a menu-bar utility or a regular Dock app.
Six recent colors in the menu bar
Reopen and copy recent results, clear history, or start another pick.
Tool shortcuts
Open the library, tonal matrix, contrast checker, settings, or guide from the menu.
Four global shortcuts
Customize picking, library, matrix, and contrast actions while Weeko Color is running.
Conflict detection
Find duplicate app shortcuts and known macOS conflicts before they become unreliable.
Back up deliberately, merge safely
JSON is created only when you export; import validates and merges rather than replacing the active library.
Complete library backup
Include recent colors, favorites, custom names, and pinned state.
Validated merge
Check version and data, migrate older backups, and skip duplicate colors.
Clear limits
Accept files up to 10 MB with up to 500 recent and 2,000 favorite colors per import.
Visible progress
Show import and export progress, then report how many colors were added.
Core color tools first. Pro when the workflow expands.
Free covers screen picking, library basics, four CSS formats, one saved palette, contrast checks, simulations, and JSON library backup. Pro unlocks the complete developer-output and palette workflow.

LOCAL BY DESIGN
Your color work does not need an account
Weeko Color uses Screen Recording permission only to read the pixel under your pointer. Picking, conversion, palette generation, contrast analysis, and library storage happen on this Mac, and color data is not uploaded automatically.
Screen access is used only while you deliberately operate the picker; Weeko Color does not save a screen recording.
Recent colors, favorites, and analysis state remain in the local app container until you remove them.
A JSON backup is created only when you explicitly export the library; there is no account or cloud sync.
Questions before your first pick
Why does a color picker need Screen Recording permission?
macOS protects access to screen pixels with this permission. Weeko Color uses it only while you deliberately operate the screen picker to read the pixel under the pointer.
Does Weeko Color upload my screen or color library?
No. Picking, conversion, palette generation, contrast analysis, history, and favorites are local. A backup file is created only when you choose to export it.
Which color formats can I copy?
There are 22 formats spanning Web and CSS, Android, Flutter, Apple platforms, HarmonyOS, Python, Java, .NET, OpenGL, Unity, and raw numeric values.
What happens when recent-color history is turned off?
Weeko Color stops adding new history entries. Existing recent colors and favorites remain until you delete or clear them.
Does contrast optimization guarantee accessibility compliance?
No. It targets normal-text WCAG AA or AAA ratios and provides a practical preview, but final products still need testing in their real interface and with users or assistive technology where appropriate.
Is color-vision simulation a medical test?
No. It is a design aid for previewing how a text and background pair may change under four simulated color-vision conditions.
Will importing a backup replace my current colors?
No. Weeko Color validates and merges the backup, skips duplicates, and reports newly added colors.
Can Weeko Color sync colors between Macs?
Not in the current version. There is no account, iCloud sync, team sharing, or automatic cloud backup.
