For example, if you create a tree shape, you should either name it with a different name such as, You can use the actual name of the main colors in your code such as, You can use arithmetic with color names to achieve shades of a color such as, You can use decimal points for more shades such as, If you are familiar with technical aspects of color representation in computing, you can use the.
