Frequently asked questions
What is the difference between HEX and RGB color models?
HEX (hexadecimal) represents colors as base-16 strings prefixed by a hash (e.g., #FF5733), whereas RGB defines colors as three integer channels (Red, Green, Blue) from 0 to 255. Both specify identical colors in the sRGB color space.
Does this tool support HEX colors with alpha transparency?
Yes. You can input 8-digit HEX codes (like #FF000080), and Toolhast will accurately calculate the alpha channel and output standard CSS rgba() values.
Can I input 3-character shorthand HEX codes?
Yes. Shorthand codes like #FFF or #F00 are automatically expanded to full 6-character hex equivalents (#FFFFFF and #FF0000) according to W3C CSS specifications.
What is HSL and why do designers use it?
HSL stands for Hue (color angle 0-360°), Saturation (intensity 0-100%), and Lightness (brightness 0-100%). It is much more intuitive for human designers when creating harmonious color palettes, hover states, and dark mode variants.
Does this color converter work offline?
Yes. All mathematical conversions and color swatch renderings run client-side in your web browser with zero network calls.
Is this color conversion tool free?
Yes, 100% free with unlimited conversions and instant one-click clipboard copying.
