Before building our HEX to RGBA converter, we checked how one of the most-referenced color code sites — htmlcolorcodes.com — actually handles converting between formats.
A hex to rgb converter that's a different page from rgb to hex
The two directions live at separate URLs: /hex-to-rgb/ and /rgb-to-hex/. If you're not sure which direction you'll need next, that's a page navigation away. Ours shows HEX, RGB, RGBA, and HSL simultaneously — edit any one and the other three update immediately, no direction to pick in advance.
An rgba color picker that isn't actually a picker
The color picker on that site lives at a separate /color-picker/ URL entirely, while the converter itself expects you to type a code and click "Convert." Ours has the native color picker built directly into the converter — pick a color and every format updates live, no button, no second tool.
hex to rgba — support for the "a" part
We didn't find any mention of alpha, RGBA, or 8-digit HEX support on the page we checked — it converts fully opaque colors only. Transparency is common enough in real CSS work (overlays, hover states, border tints) that we built an alpha slider in from the start: drag it and the 8-digit HEX and RGBA output update together, live.
