This article will introduce several methods and tools for you to query CSS color values.

The value range of the three color values ​​​​of red, green, and blue is 0~255. For example, rgb(255, 255, 255) represents white, and rgb(0, 0, 0) represents black.
  3. RGBA format: Add an A parameter to RGB to indicate transparency, and the value range is 0~1. For example, rgba(255, 255, 255, 0.5) represents translucent white.
