Image Color Picker
This lesson is part of Web Developer Tools · All levels
Summary
Image color picker takes the color value of a particular pixel on an image and displays it in HEX, RGB, or HSL format. This tool is useful for matching brand colors, taking colors from design references, or checking pallet consistency. For accurate results, take a sample from a flat area and avoid the edges exposed to anti-aliasing.
Key points
- HEX writes the color as #RRGGBB in base sixteen
- RGB uses three values 0-255 for red, green, and blue
- HSL facilitates adjustment of hue, saturation, and lightness
- Take a sample from a flat area so it's not affected by gradation or noise.
- JPEG compression can change the original color value around the edge
