Color to Code: limits and things worth knowing

Alpha channel position differs by platform and is a frequent source of wrong colours: Android uses ARGB with alpha first, while CSS #RRGGBBAA puts it last.
Swift's UIColor and SwiftUI's Color take components as 0-1 floats rather than 0-255 integers.
Flutter uses 0xAARRGGBB and requires the alpha byte — omitting it produces a fully transparent colour, which reads as the widget simply not appearing.
Android XML colours can be written #RGB, #ARGB, #RRGGBB or #AARRGGBB, and the short forms expand by repeating each digit.

Is it private and secure?

Your privacy is built in. Color to Code runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
