Fixed an issue where hex colors would be replaced by the closest regular color. You can add colors to the config.yml by typing a hashtag followed by 6 numbers/letters.

This will work
"#105020"
"#a04d04"
"#Ad4F0c"

This will not work:

"a040a0a" Missing the hashtag
"zA50f0a" only letters a-f are allowed
