If you haven't already heard about it, Adobe Color is a great tool to help you out creating color schemes!
How to use Adobe Color tool
Color Wheel: By selecting pre-existing color rules (top left) and playing around with the color pointers on the wheel, you can make your own color schemes. Create from image: Another option is uploading an image (camera icon at the top right) and the tool would generate color options detected in the image.
How do you use these schemes?
Each color has:
RGB values - used for digital files (for example: in Microsoft Office documents)
HEX code - also used for digital purposes (usually in web apps)
CMYK values - used in graphic files for press or print
