As I’m required to create visually creative and stunning dashboards and reports, and sometimes don’t have access to the Ridgian resident Lead Creative, and also sometimes the customer doesn’t have a defined corporate colour palette  (or Color to our across the pond friends) I have to throw one together, if the standard out of the box items doesn’t quite fit the bill. One drawback to this I’m ridiculously colour-blind, Red/Green Blue/Purple and many more it seems. One of my stock websites to go to is the Adobe colour wheel, with colour rules, like shades, complementary etc.
Great for those, “mmmh what goes with lime green?” moments. (Note: nothing goes with lime green).
Another great link is the W3 schools one, good for getting those Hex colour values that SSRS & Power BI likes.
