Script does not seem to include 'tron' as color

[zbeeble49]

The script does not include 'Tron' color in the version I have fetched from git.

local -a valid_colors=("90ssummer" "adwaita" "aubergine" "aurora" "berriez" "black" "blue" "bluegrey" "bordeaux" "brown" "canonical" "cyan" "cyberneon" "cyberpunk" "darkblue" "discodingo" "fitdance" "green" "grey" "indigo" "magenta" "manjaro" "mint" "orange" "pink" "purple" "red" "synthwave" "teal" "vermillion" "violet" "void" "white" "yaru" "yellow")

Have added 'tron'

local -a valid_colors=("90ssummer" "adwaita" "aubergine" "aurora" "berriez" "black" "blue" "bluegrey" "bordeaux" "brown" "canonical" "cyan" "cyberneon" "cyberpunk" "darkblue" "discodingo" "fitdance" "green" "grey" "indigo" "magenta" "manjaro" "mint" "orange" "pink" "purple" "red" "synthwave" "teal" *"tron"* "vermillion" "violet" "void" "white" "yaru" "yellow")

And it works as expected.
