What this collection covers
The jobs these tools handle
Design work needs colors in whichever notation the next tool expects, and it needs them to pass accessibility review. Convert between HEX, RGB and HSL with alpha where you need it, check a text-and-background pair against WCAG AA and AAA thresholds, pull colors out of an image or build a palette from a base tone, and generate the gradient, shadow, or filter CSS ready to paste into a stylesheet.
Choose the color tool by the design decision
Converting notation, selecting a palette, and checking accessibility answer different questions. Use the checker for a pass/fail decision rather than judging contrast by eye.
You need readable text and interface colors
Test a foreground and background pair against the displayed WCAG thresholds before shipping it. Open WCAG contrast checker
You need related colors from one starting point
Generate a coordinated palette, then validate the combinations you plan to use for text. Open Color palette generator
Turn an inspiration image into an accessible palette
Sample first, organize the colors second, and test real foreground/background pairs last. A pleasant palette does not automatically produce readable text.
1. Sample the source
Pick representative pixels from the image and save the exact values you want to explore. Open Image color picker
2. Build related options
Use a sampled color as the base and compare several coordinated palette strategies. Open Color palette generator
3. Validate actual pairs
Check every text/background combination you intend to use, including smaller text and muted states. Open WCAG contrast checker

Tips for larger files
Very large files can need more memory, especially on a phone. Keep originals, start with a small batch, and close other heavy apps or tabs if a tool feels slow.
