Jack Just ConstructionLogo Design Contest

Thanks for this - could the colours be brightened?

sorry I can't use jcc because it's a concept from another designer from blind contest.

Could you also please try design a logo with JJC so that the logo can have meaning to it when it doesn't have words beside it or underneath it? Thank you.

Thank you. All our signage will be on dark grey, could you please show what these look like with this background? |
Would it also be possible to see this design without the gradient colours?
