From User to Designer: Applying Color Theory to Understand Jira

You have done a great job, I like the presentation layout and your idea with the colors for the header. However, more attention should be given to contrast and color accessibility. You can use tools in Figma to improve the WCAG level.

In my opinion, using pure white is a bad idea because too high a contrast between design elements might give an unsettled and messy impression. Black and white create the highest contrast possible.

I understand that the example you created is only to showcase the colors. Unfortunately, it spoils the overall picture of your work. It would be great to work a bit on the typography in your example.
