CSS colors

CSS colors can be written with names, hexadecimal notation, or color functions.

Minimal example

.notice { color: #245; background-color: rgb(240 245 255); }

Use a named color for quick experiments and hexadecimal or functions when you need precise values.

Common mistakes

• Check contrast between text and background.
• Do not rely on color alone to communicate meaning.
• Remember that a color value without a property has no effect.
