Brandwashed

Where I grew up, if you needed something stuck on a wall, you reached for the Prestik. It did what it said it would do. You pressed - it stuck.

Then I headed north to find that the sticky poster-to-wall adhesive market is cornered by a product called Blutack. Blue and tacky - that's the best the Bostik marketers could come up with. It doesn't really give them much scope for development, now does it? Any old adhesive company could easily just decide to tip a different dye into the same sticky recipe and invent Blacktack (now there's a catchy brand name).

Call a product by what it helps you to do or how it works, not by what it looks like. Can anyone think of another product that is arbitrarily only available in one colour?
