Total Air SolutionsLogo Design Contest

#12, #28 - what would it look like on a black background? Need to make a version that visible on a black background.
My sheet metal workers will be wearing black T shirts with the logo on the left chest (and possibly a large logo on the back).

Thank you for giving feedback.

I did submitted some variation and put the logo on black color background but it didn't show up in the contest.
