Frequently asked questions
What is the difference between HEX and RGB?
They represent the same colors — HEX is a compact 6-digit hexadecimal notation (#RRGGBB), while RGB writes each channel as a decimal 0-255. Both map 1:1.
When should I use HSL?
HSL (hue, saturation, lightness) is friendlier for design tokens — varying just the lightness or saturation produces predictable shades, which is hard with HEX or RGB.
What is the alpha channel?
Alpha is opacity (0 = transparent, 1 = opaque). In CSS use rgba() / hsla() or the 8-digit HEX form #RRGGBBAA.
Is HSV the same as HSL?
No. Both share hue and saturation, but HSL uses lightness (50% = pure color) while HSV uses value/brightness (100% = pure color). HSV is common in color pickers, HSL in CSS.
Why does my color look different on another screen?
Color profiles and display calibration vary. For brand-critical work, specify in a wide-gamut profile like P3 and test on target devices.
