Here’s how to set the background color of a message you are composing in macOS Mail.

Choose Colors to Keep Text Legible

When you’re playing with document background colors, be sure to select a text color and size that ensures your message text is legible. If you’re using a dark background color, for example, you may want to experiment with a light text color.

Color Wheel: Choose first the darkness of color with the bottom slider and then tap on the wheel to select a color. If the slider is too far to the right, you might think you can only choose black. Don’t be fooled; you have a full choice of colors. You can use the eyedropper if you want to get a close-up view of the color choices.Color Sliders: Choose the Slider icon and then use the drop-down menu to choose a grayscale slider, RGB sliders, CYMK sliders, and HSB sliders. You will see the percentages change as you move the sliders.Color Palettes: Choose from set palettes including web-safe colors, crayons, “Apple,” “Developer,” and others.Image Palettes: Choose from a spectrum palette or create a new image palette from a file or the clipboard.Pencils: Choose from colored pencils.
