Is there a preferred shirt color you want to use? How many print colors do you want to use?

Hey,
Submitted a few designs.
Please have a look and provide feedback.
Certain doubts, are you open to color or just the gray tones mentioned on the brief page? Also, how many print colors, 1-4?
Preffered t-shirt colour?
Do let me know, will do changes and work on new concepts accordingly.
Regards,
Jayneel

as far as the T-shirt color goes, I plan to put this on black grey and red. The print color should be a good contrast to the shirt. So for black, you can use white, red, or yellow...so forth and so on.
