Common Questions

Color harmonies are combinations of colors that are visually pleasing based on their position on the color wheel. Complementary colors are opposite each other, analogous colors are adjacent, triadic colors are evenly spaced by 120°, and tetradic uses four colors in a rectangle.

Split the 6-digit hex code into three pairs and convert each from hexadecimal to decimal. For example, #FF5733 → R:255, G:87, B:51. Our tool does this instantly — just enter your HEX in the field and RGB and HSL update automatically.

WCAG 2.1 requires at least 4.5:1 for normal text (AA) and 7:1 for AAA. Large text (18pt+) needs 3:1 for AA. Our contrast checker shows your exact ratio and WCAG grade in real time. Always test both light and dark backgrounds.

RGB describes colors by red, green, and blue light (0–255 each). HSL uses Hue (0–360°), Saturation (0–100%), and Lightness (0–100%). HSL is more intuitive for designers because you can easily adjust brightness without changing the color family.
