Sooo I keep buying clothes that are the wrong colour because of my colourblindness, can anyone help me out?

I know this sounds a bit stupid, but I went out the other day and copped what I believed to be a nice faded grey sweatshirt from H&M (going for that cheap yeezy look), and only found out today that it is in fact green instead, and I feel a bit stupid now.I know most people just say to just look around and you'll find the right stuff, but if you're bad at colours it's a real setback.So all I wanted from you guys is if you could possibly share links to any UK based clothing stores with either Earth-tone or grey t-shirts/sweat shirts.
