trying to understanding colors :(

back to frustrating mood again
it is very hard to see colors i keep trying but when test re produce colored images i just can't get it

i had figure out how to do value study gray scale is my friend now that is big step for me i am very happy that i can do value studies  

but i just want more i just want to learn and train my eyes to see colors i want to do color study and hopefully master studies someday soon  

i just dont know what to do 

maybe start with simpler images IDK

ok i am just breathing out my thoughts nothing more no idea what i need to do and learn at my current level that can help me to improve
currently just exploring stuff and experimenting more stuff    

it's just very frustrating to fail over and over again understanding colors but i will keep trying
there must be something to get colors I haven't discover yet 

ok ok i will keep re trying doing color studies hopefully that little step will come from practice will try research simple images maybe still life for I had failed very badly trying study nature (landscape) it is very hard to get all the variation in colors 
i think I need some simple images with low number of colors variations and shapes to start my journey with colors and do color studies   

if you have any exercise or advice how to see colors or copy colors please help
