I'm not against the colours. I think they are great attention grabbers, and would have little problem using a yellow, red or blue DSLR myself. (Maybe I'd draw the line at pink).
I was just surprised at how small and bare-bones the display was - a red Pentax cloth draped over a small table that they seem to be sharing with someone else, no Pentax flashes, no 645D, no Pentax tchotchkes
.
But a positive is that they had gear on the table like the GR, the K-3 and the K-50, and people could probably handle it all.
