How to Pick Colors for Design Projects

How to pick colors for design: understand HEX, RGB, and HSL codes, build a cohesive palette, and keep your design accessible.

HEX, RGB, and HSL Explained

Color codes are how screens describe colors. HEX is a six-digit code such as #2563eb that mixes red, green, and blue amounts. RGB uses the same idea as three numbers, like rgb(37, 99, 235). HSL instead describes hue, saturation, and lightness, which makes it the easiest system to adjust by feel.

How to Grab Any Color From Your Screen

Step 1: Open the free Color Picker.

Step 2: Click anywhere in the color area to choose a shade.

Step 3: Copy the HEX, RGB, or HSL code with one click and paste it into your design tool.

Building a Cohesive Palette

Start with one base color, then choose two or three supporting colors from the same hue family or from opposite sides of the color wheel for contrast. Keep one neutral color, like white, gray, or black, for backgrounds and text. A simple rule: use one main accent color for buttons and links, not five.

Accessibility Notes

Check that text stands out from its background. Dark text on a light background, or light text on a dark background, keeps your design readable for everyone. Avoid pairing red and green alone, since color-blind readers may not see the difference.

Frequently Asked Questions

What is the difference between HEX and RGB?
They describe the same red, green, and blue mix in different formats. HEX is compact and widely used in code, while RGB uses three numbers from 0 to 255.
Can I copy color codes from any image?
Our picker works in your browser on any visual element. For images, open the image and use the picker to sample pixels directly.
How many colors should a design use?
A base color, one accent, and one neutral color cover most clean designs. More colors usually add noise, not value.
