Color System

Few things to consider:

• The yellow system color is not optimal looking at UI examples. Can be closer to pure yellow.
• On the UI presentation, would be great to see a more complete screen example of how all color combinations work together. Now its a bit hard to understand.

I agree with everything Gene says. I would add that it would be ideal for you to show how your colors work in the WCAG section (not just explain what it is, but also display the scores obtained with the chosen colors; this will help reinforce why you have chosen those colors).

Overall, nice work! Keep going 💪

Under WCAG compliances 2.1, as you have already mentioned color contract affects in improving the readability, but here the colors you have used are not the good examples as they are not passing the ratio defined for AA,AAA. And to check that either you can use figma plugin or can check on this website "accessible web"
