About color formats
HEX represents color as a 6-digit hexadecimal code (e.g. #2F5DFF), commonly used in CSS and design tools. RGB expresses color as red, green and blue intensity values from 0–255. HSL (Hue, Saturation, Lightness) describes color in a way that's often more intuitive for adjusting brightness or vividness without changing the underlying hue.
When to use each format
- HEX is the most common format in web design and CSS stylesheets
- RGB is useful when working with image editing software or pixel-level color data
- HSL makes it easy to create color variations — just adjust the lightness or saturation while keeping the hue constant
Frequently asked questions
What's the difference between HEX, RGB, and HSL?
HEX (#3366FF) is a compact hexadecimal code used mostly in CSS and design tools. RGB (red, green, blue, 0-255 each) is how screens mix light to create color. HSL (hue, saturation, lightness) describes color the way people naturally think about it, making it easier to tweak shades and brightness.
Why does the same color look slightly different on different screens?
Screens vary in calibration, brightness, and color gamut, so the exact same HEX or RGB value can render with subtle differences between a phone, a laptop, and a printed design. For critical branding work, always check colors on multiple devices.
What is alpha or opacity in RGBA/HSLA?
The "A" stands for alpha, a value from 0 (fully transparent) to 1 (fully opaque) that controls how see-through a color is - useful for overlays, shadows, and layering elements in web design.
