results of black t-shirt experiment
Well, my two black t-shirts arrived, and despite there being huge blocks of pure white on black, they look totally fine!
The <a href="http://www.redbubble.com/people/science/clothin... Inside</a> one worked out really well, as it doesn’t have such large areas of white, but even the <a href="http://www.redbubble.com/people/science/clothin...; one worked out well I think.
The upshot of it all seems to be that it’s not as bad as you might think to use designs with big blocks of white on black.
