Sales & Returns Sample Report

I almost always make my own palette rather than using a built-in one, but that is just because I am rather particular. If I don't have an organizational color palette to work from, I usually default to blue and gray or use viridis as inspiration. Lately, I'm enjoying using the free Adobe color tool to check my palettes for color blindness conflicts. But I also still just grab screenshots and put them in Coblis as another check. There are also browser extensions to help you check color blindness and other color contrast issues. I did check the first five colors of the default palette and they were ok as far as most types of colorblindness, and all colors had sufficient contrast to be used in charts against a white background.
