Frequently Asked Questions

Learn more about color spaces, gradients, and modern UI design trends.

A HEX color code is a 6-symbol code made of up to three 2-symbol elements. Each of the 2-symbol elements expresses a color value from 0 to 255. It is widely used in HTML and CSS.
RGB defines colors based on Red, Green, and Blue light combinations. HSL defines colors based on Hue, Saturation, and Lightness, which is often more intuitive for designers to manipulate.
A mesh gradient is a complex gradient created by blending multiple colors using radial gradients from different points. It creates a smooth, liquid-like, modern aesthetic often used in high-end UI design.
Glassmorphism is a UI design trend that mimics the look of frosted glass. It relies on a semi-transparent background, background blur, and a subtle light border to create a sense of depth.
