Logos not for the colour blind

For anyone not familiar with these patterns, they are used to test peoples vision for colour blindness. The Dennis Murphy ( number 2 ) logo especially is nearly exactly what a real test pattern would look like, right down to the colours used.

Anyone with normal colour perception will see an orange M amongst the green dots, while the 8% or so of people with colour blindness will see only a ball of dots. The M would not be visible.

What do you think?

Quite a move to exclude 8% of the population from ever truly seeing your logo. Either that or quite an oversight.
