Color is an important part of any interface design, and knowing how to choose colors can make or break your project. The 60–30–10 rule will help you do just that!

This is the secondary color or complementary color. You’ll use half as much of this color as you did your main hue. This is used on major elements such as text, carousels, and other important features
The secondary color supports the main one but is still different enough to create contrast.
10%
This is the accent color. This color can be used in buttons, pop-ups, highlights, etc.
Bright, vibrant colors are a great way to add visual interest. They can help draw attention to specific areas of a page or make it feel more alive overall.
