Question 1

What color formats does this tool support?

Accepted Answer

Our color picker supports all major color formats: HEX (#RRGGBB), RGB (red, green, blue), RGBA (with alpha/opacity), HSL (hue, saturation, lightness), HSLA, HSV (hue, saturation, value), CMYK (cyan, magenta, yellow, black), and HWB (hue, whiteness, blackness). You can instantly convert between any of these formats.

Question 2

What are color harmonies and how do I use them?

Accepted Answer

Color harmonies are combinations of colors that work well together based on color theory. Our tool generates 7 harmony types: Complementary (opposite colors), Analogous (adjacent colors), Triadic (3 colors evenly spaced), Tetradic (4 colors in rectangle), Split-Complementary (base color + 2 adjacent to complement), Square (4 colors evenly spaced), and Monochromatic (same hue with varying lightness). Simply select a harmony type and click "Generate" to create a color scheme.

Question 3

How does the WCAG contrast checker work?

Accepted Answer

The WCAG contrast checker tests if text is readable on a background by calculating the contrast ratio between two colors. It shows compliance with WCAG 2.1 standards: AA requires 4.5:1 for normal text (3.0:1 for large text), while AAA requires 7.0:1 for normal text (4.5:1 for large text). Meeting these standards ensures your designs are accessible to users with visual impairments.

Question 4

When should I use CMYK instead of RGB?

Accepted Answer

CMYK (Cyan, Magenta, Yellow, Black) is used for print design because printers mix these four inks to create colors. RGB is for digital screens (websites, apps, displays). If you're designing something that will be printed (business cards, brochures, posters), convert your colors to CMYK to ensure accurate color reproduction. Our tool shows you the CMYK values for any color you pick.

Question 5

How do I save and reuse my favorite colors?

Accepted Answer

Click the "Save Current" button in the Saved Colors section to store your current color. Saved colors are stored in your browser's local storage, so they persist between sessions. Click any saved color to instantly load it back into the picker. You can delete saved colors by hovering over them and clicking the × button.
