How do I convert HEX to RGB?
Split the hex code into three pairs and convert each from base 16 to base 10. So #FF8800 becomes R=255, G=136, B=0. The converter does this automatically. Three-digit shorthand like #F80 expands to #FF8800 by doubling each digit. RGB values are always in the 0-255 range, regardless of how the hex string is written.
What is the difference between RGB and RGBA?
RGB has three channels (red, green, blue), each 0-255. RGBA adds an alpha channel for transparency, where 0 is fully transparent and 1 (or 255) is fully opaque. CSS uses rgba(255, 136, 0, 0.5) for half-transparent orange. Use RGB when transparency is not needed and RGBA when blending the colour over a background.
How is HSL different from RGB?
HSL describes a colour as Hue (0-360 degrees on a colour wheel), Saturation (0-100 percent), and Lightness (0-100 percent). It matches how designers think about colour: pick a hue, then adjust intensity and brightness. RGB is how monitors render colour. The converter translates between them so you can edit in HSL and ship in HEX.
What is CMYK used for?
CMYK is the print colour model: Cyan, Magenta, Yellow, Black, each as a percentage of ink coverage. Print shops require CMYK files because their inks are subtractive, while monitors are additive (RGB). Converting from RGB to CMYK is approximate because the gamuts differ; bright neon colours on screen often look duller in print.
Why does the same hex code look different on different screens?
Monitors vary in colour calibration, brightness, and gamut (sRGB, P3, Adobe RGB). The numeric value is identical, but the rendered colour can shift noticeably. Professionals calibrate displays and use ICC profiles for accuracy. For web work, design in sRGB, since most browsers and devices assume that gamut by default.
What is HSV and when is it useful?
HSV (Hue, Saturation, Value) is similar to HSL but uses Value instead of Lightness. Value 100 means full brightness, while in HSL, 100 lightness means white. HSV is common in image editors and colour pickers because adjusting Value keeps the colour vivid, while HSL washes towards white. The converter handles both.
