User quotes:
I am designing leaflets for our local trail map. I was dismayed to learn that the colours we had chosen for the three trails - red, green and purple - were going to cause problems for so many people! However, I then discovered your marvellous Vischeck, and with Photoshop and this fabulous upload-and-check facility I have re-coloured all the trails. I just worked on the colours until they appeared completely distinguishable in all three Vischeck modes. Easy, and very exciting. Many many thanks for solving the problem in such a user-friendly way.
