Frequently Asked Questions
How do I convert HEX to RGB?
Split the 6-digit hex into pairs and convert each from hexadecimal to decimal. #FF5733: FF=255 (R), 57=87 (G), 33=51 (B) → RGB(255, 87, 51). The calculator does this instantly.
What is the difference between 3-digit and 6-digit HEX codes?
3-digit hex (#RGB) is a shorthand where each digit is doubled: #F53 = #FF5533. Only possible when each pair has identical digits. Both formats represent the same 16.7 million colors.
What is HSL and why is it useful?
HSL (Hue 0-360°, Saturation 0-100%, Lightness 0-100%) is more intuitive for design. To make a color lighter, increase L. To desaturate, decrease S. Much easier to reason about than tweaking individual RGB values.
What is the RGB value of white and black?
White = RGB(255, 255, 255) = #FFFFFF. Black = RGB(0, 0, 0) = #000000. All RGB values equal means a shade of gray.
Can I enter an 8-digit HEX code for colors with transparency?
Yes. 8-digit HEX (#RRGGBBAA) includes an alpha (opacity) channel. AA=FF means fully opaque, AA=00 means fully transparent. The tool converts 8-digit hex to RGBA format.
