Hello 130amEST,
I'm happy to tell you, your map has been Accepted!
The theme is original, there are a few maps related to colours, but none exactly like this.
The build is good, you represented the theme well in the build, as it is a very broad theme.
The parkour is varied, you utilized the blocks well to create enjoyable and original jumps, with little to no repetition which is good.
The length and difficulty are good for an easy map.
I did add a couple of directional signs as a few areas weren't clear, I can show you these or send you screenshots if you are interested.
Thanks for submitting your map! I hope to see more maps from you in the future.
