Frequently Asked Questions

How does RGB convert to HEX?

Each RGB value (0-255) converts to a two-digit hexadecimal number (00-FF). For example, RGB(255, 87, 51) becomes: 255=FF, 87=57, 51=33, resulting in #FF5733. The conversion is purely mathematical.

Should I use uppercase or lowercase HEX?

Both work identically in CSS and HTML - #FF5733 and #ff5733 display the same color. Uppercase is traditional and often preferred for readability, but the choice is purely stylistic.

Can I convert RGBA with transparency?

Standard 6-digit HEX codes do not support transparency. For transparency, you can use 8-digit HEX (like #FF573380) or keep using rgba() format in CSS, which modern browsers fully support.
