The tag implication #51808 flat_colors -> colored has been rejected.
Reason: If there are flat colors, there are colors in the post, therefore the post should be tagged as colored. However, there are many posts tagged as flat colored, but not colored, see flat_colors -colored
Overall self-explanatory
EDIT: The tag implication flat_colors -> colored (forum #376021) has been rejected by @slyroon.
