Frequently Asked Questions

How does RGBA to HEX conversion work?

RGBA colors are converted to 8-digit hexadecimal format where the last two digits represent the alpha channel. For example, rgba(255, 0, 0, 0.5) becomes #FF000080.

What is the alpha channel?

The alpha channel controls transparency, ranging from 0 (fully transparent) to 1 (fully opaque). In hex format, it's represented as 00 (transparent) to FF (opaque).

Can I use 8-digit hex colors in CSS?

Yes, modern browsers support 8-digit hex colors for specifying transparency. It's a more concise alternative to using rgba() notation.

How do I convert back to RGBA?

To convert from 8-digit hex to RGBA, split the hex into RGB components and convert the last two digits to a decimal between 0 and 1 for the alpha value.
