Step one: Find your brand color. If you have a logo, start with its colors.

Step two: The 60-30-10 rule. 60% primary color (background), 30% secondary color (sections), 10% accent color (buttons and links).

Step three: Test readability. Text on background must have enough contrast. Light gray text on white = eye strain.

Step four: Use ready-made palettes. Sites like Coolors or Adobe Color offer ready palettes. You don’t need to spin the color wheel yourself.

Tip: For a blog, the simplest and most professional combination is: white/cream background, dark text, one accent color for buttons.
