Seems to be a bit of misunderstanding Purple for Girls Green for Boys Tye dye would look nice but that would increase the cost of making the T-shirt alot.

@ Anonymous: It does look a bit weird doesn't it, but that is how far the wheels were apart on my reference image from the early TV shows so I think I will keep them as is.

Thank you to everyone for your comments. @ Angie: I personally like the silhouette design and it is a conscience decision rather than just avoiding copyright. I believe it makes the t-shirt stand out more. If I just did an exact copy of the Mystery Machine with the faces, blue colour of the van etc then people might not notice the writing is different. Also as I said previously in comments it is also a type of homage to the iPod style of black silhouette with a bold colour of and important part (In this case the hair). I don't think it is hard to tell the characters as there hairs are very different and easy to recognise, imo. I have changed Shaggys hair, so thank you for pointing that out. Though on my reference image he does have orange hair the more modern Shaggy does have brown hair. I have changed Freds lapel a bit more red but not too much, I don't think it matters that it is more-a-less the same colour as Daphnes hair.

Ok Scooby now has shades on ;), and I've lightened the t-shirt colours just a bit.

@Daniel: Thanks for the comment :). That was my fear of showing scoobys fur. But it looks better than no fur at all, I could maybe put some shades on him. I dunno if that would be appropriate though.

Frank, if you read my comment below that was exactly the idea, Daphne Purple for girls, Shaggy Green for the guys ;) but thanks for liking the colurs =].

Thank you to everyone for your comments! @K Safari: You are a genius, the blue window is a great touch! Pink and blue look good for the backgrounds, but for the image I have chosen Daphne Purple for the girls and Shaggy Green for the boys. Pink and blue also work well, most bright colours will work as a background. Just have to find the ones that will appeal to most people. Not forgetting the t-shirt doesn't have to be just two different colour shirts.

Updated design based on your comments. @ Frank: Yeah I wanted more to show it was Scooby, but I thought It might be too much to show his fur, but I think it actually looks good. And your not the only one to show dislike to the background, and though I love the blue, customer is always right so I have gone with a brown as orange clashed too much. @Clint: Thanks =] @Darcy: The silhouettes are there as like a iPod style thing, being able to tell the characters without a face and avoiding copyright. I think taking away the silhouettes leaves too much of a gap and takes away from the design.

Thanks for the idea's. Design is now updated with colours and style.
