Color Picker: A Practical Guide
Use Color Picker to select a color and read its hexadecimal and RGB representations. It is useful when matching a simple web color across styles. The tool is not a screen eyedropper, contrast checker or print color-management system.
How to Use Color Picker
- Choose a color in the browser’s color control.
- Select Show color.
- Read the HEX and RGB values.
- Test the color in its actual design context.
HEX and RGB Describe the Same Channels
A six-digit hexadecimal value contains red, green and blue channel values. RGB expresses those channels as decimal values from 0 to 255. The same channel combination can be written in either notation.
Perceived appearance depends on the display, surrounding colors and color handling. A numeric color match does not guarantee print matching or accessible contrast against a particular background.
Worked Example
The color #2563EB corresponds to rgb(37, 99, 235). You can use either representation in an appropriate CSS color property.
For a button, test both the background color and the text contrast rather than choosing a color in isolation.
Apply supported image adjustments: use the Image Editor.
Choose a readable mark in context: use the Watermark Image.
Checks and Common Mistakes
- Check contrast separately.
- Do not assume screen and print appearance match.
- This form does not provide an alpha channel.
- Use a screen-eyedropper tool when sampling a screenshot is required.
Frequently Asked Questions
Can I sample any pixel on my screen?
This workflow uses a color-selection control, not a guaranteed global eyedropper.
Does it check accessibility?
No. Use a suitable contrast check for foreground and background combinations.
Does it output CMYK?
The current result provides HEX and RGB, not a print CMYK conversion.
