Frequently Asked Questions
What is the difference between HEX and RGBA color codes?
HEX uses base-16 math to represent Red, Green, and Blue channels. RGBA uses base-10 integer values (0-255) for color channels and includes an extra Alpha channel (0.0 - 1.0) to control transparency.
Does this converter support 8-digit HEX alpha codes?
Yes. The converter parses standard 6-digit hex values and can output 8-digit hexadecimal colors (e.g., #4F46E5CC) containing transparency channels.
How do you calculate RGB from a HEX code manually?
Split the hex string into three pairs of two digits (R, G, B) and convert each pair from hexadecimal to a decimal number. For example, FF becomes 255, and 00 becomes 0.
