avrum's rainbow tshirt recolour

rainbow t-shirt texture, made by me, avrum! EXTRA INFORMATION ABOUT THIS: you can recolour the base part ; patterns not currently supported ; recolouring of the rainbow itself not currently supported. if theres interest, i can make both of these in the future, though ^ LET ME KNOW IF IT BREAKS - THEN ILL TRY TO FIX IT ! it currently exists as a variant of a regular tshirt in order to easily support layering with all of the jackets ; however if it conflicts with other mods or you simply would prefer a standalone, i can do that too. cheers and send me requests for cute mods!
