it would be easier if this bitmap has size 3x3 pixels (without any antialiasing etc, just pure bitmap). 

then youll need some scripting -> iterate through all the pixels and if e.g pixel's hue <15 and >90 then add "red" to the strings/int list. 

pseudocode : 

create list of strings

load bitmap from file path

get bitmap height

get bitmap width

count pixels -> (width*height) -> create a new int (pixelCount)

check every pixels color :

• loop till i = pixelCount-1
• if hue < 20 and >80 then add "red" to string list
• if hue >20 and <40 then add ... etc.

output string list
