red and other colors

Quick answer：

The term 'red and other colors' refers to the classification of hues in the visible spectrum. Red is one of the primary colors, which are the most basic colors from which all other colors can be mixed. Other colors include secondary colors, which are formed by mixing two primary colors (such as red and blue to make purple), and tertiary colors, which are formed by mixing a primary color with a secondary color. The color spectrum encompasses all these hues, ranging from red to violet, with shades of each color in between.
