Complete Guide to Color Tools
SheetEdit Tools offers free online color tools including RGB picker, HEX converter, palette generator, contrast checker, gradient generator, and more. This guide covers use cases and tips for each tool to help you work efficiently with colors and design.
What are digital color tools?
Digital color tools help you specify, convert, compare, and combine colors on screen. A color can be described in many notations (HEX, RGB, HSL, etc.); tools keep values consistent so designers and developers share the same “source of truth.” Accessibility checkers ensure text stays readable against backgrounds (e.g., WCAG contrast).
Tool overview
RGB color picker
Adjust R, G, B or H, S, V values for precise color selection. Supports HEX input and copy. Ideal for brand colors and design specs.
Format converter
Convert between HEX, RGB, HSL, HSV, CMYK, and more. Useful for design collaboration and dev handoff when unifying color formats.
Palette generator
Generate complementary, analogous, triadic, and other schemes from a base color. Great for quick color harmony and design exploration.
Contrast checker
Check foreground/background contrast against WCAG accessibility standards. Essential for accessible design.
Gradient generator
Create linear or radial gradients and export CSS. Useful for backgrounds, buttons, cards, and other UI elements.
Image color picker
Pick colors from uploaded images. Extract palettes from reference images and brand assets.
Color blender
Blend two colors by ratio to get intermediate shades. Useful for fine-tuning and creating transition colors.
HSL picker
Adjust hue, saturation, and lightness for intuitive color control. Good for quick hue shifts and consistent brightness.
Color name finder
Enter HEX or RGB to find the closest CSS color name. Helps with communication and documentation.
Tips
- Brand colors: Use the RGB picker for exact HEX values; save in the format converter for reuse.
- Accessibility: Use the contrast checker to ensure text/background contrast ≥ 4.5:1 (AA level).
- Palettes: Generate harmonious schemes with the palette tool, then fine-tune with the color blender.
- Extraction: Pick main colors from reference images, then build full palettes from them.
All tools run in your browser. No color data is uploaded to our servers.
