What is 0xRRGGBB format?

It is the RGB color encoded as a hexadecimal integer, often used in code as 0xRRGGBB.

Why is RGB565 useful for embedded?

Many embedded displays use 16-bit color. RGB565 converts 24-bit color to a compact 16-bit value.

Color Picker for Embedded Developers

Pick a color with a clear wheel button or eyedropper, then copy values as RGB (0-255), HEX, 0xRRGGBB, and RGB565.

Why this is useful in embedded projects

Designers often share colors as HEX values, while firmware code may need decimal RGB channels or compact 16-bit color values. This tool helps you move quickly between common formats.

FAQ

Can I pick color from outside browser content?

If your browser supports the EyeDropper API and the page runs on HTTPS, yes.

Which format should I use in C/C++ firmware code?

Most codebases use 0xRRGGBB for 24-bit values. For 16-bit displays, use RGB565.

I already have HEX or RGB numbers. Where do I convert formats?

Use the Color Code Converter page for direct value-to-value conversion.
