Tertiary colours are created by mixing a primary colour with a secondary colour that is next to it on the colour wheel.
They help create smooth transitions and a wider range of shades for artistic and design purposes.
Examples of tertiary colours include red-orange, yellow-green, and blue-green.
These colours fill the gaps between primary and secondary colours, adding more depth and variation.
Tertiary colours are important in makeup, fashion, and interior design for creating harmony and balance.
