RGB to HEX Conversion

RGB (Red, Green, Blue) and HEX are two ways to represent the same color. Each RGB channel (0–255) is converted to a 2-digit hexadecimal value. HEX = # + (R in hex) + (G in hex) + (B in hex).

Common color examples:

• White: rgb(255,255,255) = #FFFFFF
• Black: rgb(0,0,0) = #000000
• Red: rgb(255,0,0) = #FF0000
• Blue: rgb(0,0,255) = #0000FF
• Orange: rgb(255,165,0) = #FFA500

How to Convert RGB to HEX

To manually convert: take each channel value, divide by 16 to get the first digit, take the remainder as the second digit. For example, 255 ÷ 16 = 15 remainder 15 → FF. 128 ÷ 16 = 8 remainder 0 → 80. Then combine: #FF8000.

Web Design Usage

CSS accepts both rgb(R, G, B) and #RRGGBB formats. HEX codes are the most common in design tools (Figma, Photoshop, Sketch) and CSS stylesheets. RGB values are useful for programmatic color manipulation and opacity (rgba adds a 4th channel for alpha transparency).
