HEX
hexadecimal color
HEX (hexadecimal) is the standard color notation on the web: a # followed by six hex digits, two per RGB channel. #FF0000 is pure red, #000000 is black, #FFFFFF is white. The 3-digit shorthand #F00 expands to #FF0000.
Color converters
Color spaces describe the same color in different number systems. HEX is the compact form used everywhere on the web; RGB is what computer screens actually emit; HSL and HSV reorganize the same RGB information around perceptually meaningful axes (hue, saturation, and either lightness or value). All conversions on this site go through a canonical sRGB representation and are mathematically exact within IEEE 754 double-precision floats.

About the formats
RGB
RGB color
RGB describes a color by its red, green, and blue channels — each on a 0–255 scale (8 bits per channel). It is what computer monitors and most digital cameras emit, and what every other web color format ultimately maps to.
HSL
HSL color
HSL describes a color by hue (0–360°), saturation (0–100%), and lightness (0–100%). It is the format CSS recommends for human-readable palettes because nudging the hue keeps the same lightness, unlike RGB where every channel matters.
HSV
HSV color
HSV (also called HSB) describes a color by hue (0–360°), saturation (0–100%), and value (0–100%). It is the format inside almost every color picker — including the one in Figma, Sketch, and Adobe — because moving the V slider down toward 0 reliably darkens any color without changing its hue.
