Frequently Asked Questions
How does RGB to HEX conversion work?
Convert each R, G, B integer (0–255) to a 2-character hexadecimal string. R:0 = 00, R:255 = FF, R:128 = 80. Concatenate with # prefix: R:0 G:255 B:135 → #00FF87.
What if a channel value is a single hex digit?
Single hex digits are padded to two characters with a leading zero. R:5 converts to 05, not 5. This is why all HEX color codes are always exactly 6 characters (plus #).
Can I convert rgba() colors?
This tool converts RGB (no alpha). For rgba(), the alpha channel (0–1) needs separate conversion to 8-digit HEX format (#RRGGBBAA). The AA hex value = Math.round(alpha × 255).toString(16).padStart(2,'0').
