How RGB converts to hex
Convert each channel (0–255) to two hex digits and concatenate: rgb(255, 87, 51) → FF, 57, 33 → #FF5733. Channels below 16 get a leading zero — rgb(0, 10, 200) is #000AC8. When all three pairs double up (#AABBCC), the color can be shortened to #ABC.
When you need hex instead of rgb()
Hex is the lingua franca of design handoffs: color pickers, brand guides, SVG attributes and most design tools expect it. CSS accepts both, so converting is about matching the format your tool or team uses — the color is identical either way.
