Where can I purchase a non-pale, yellow collared shirt?

As ridiculous as it may seem, buying a shirt in a tone of yellow that I like has proved a tricky task. Every type of yellow shirt I am presented with is either too worn/pale or dark. I want something bright.





I spotted the following poster in Clinton Cards (it's the cover of the 2008 Take That calendar, which seems to be the closest I'll ever get to seeing the yellow shirt I want):

The smarter the better.





Thanks.
