Hi again. Thanks for your efforts, really appreciated.
Can we try #47 on a square (or other shape), rather than a circle?
What I like about #47 is that the red triangle is subtle, but very effective. It's smaller than in #67, but somehow more elegant, I think. And I think I prefer the dark blue "IO" to the red one.
Could we take a look at #271 using a much lighter shade of blue? This is actually a general instruction I've sent to everyone, and also included in the revised brief.
