In addition to the primary colors, there are three secondary colors: green, purple, and orange.

Secondary colors are achieved by mixing primary colors with each other.

For example:
Blue and yellow: green
Blue and red: purple
Yellow and red: orange

Secondary colors are located opposite primary colors on the color wheel.
yellow and purple
red and green

The contrasting colors complement each other and provide a good result when used together.

Ex: yellow and purple

However, soft tones of these colors lead to better results rather than strong and bright tones. The same applies to red and green colors. Red with soft undertones, i.e. pink and green is a perfect combination. Using two contrasting colors has effects and may be disturbing. But still, we can create elegant combinations when we reduce their intensity and impact. We use definitions like light blue, light yellow, and light brown quite often when we talk about colors. Have you heard of red light? Pink number is a version of red and defines a lighter tone of red with a new name: pink.
