Basically, it doesn't matter WHAT color they are, once they are in direct Florida sunshine... Just that black speeds up the process!

I have only had a couple of occasions where I simply could NOT get any shade at all on a gig, and all presented problems. My only solution was covering the entire keyboard except the keys with a beach towel, which obviously made for quite a job getting to the buttons!

And one time, during a setup, I got I think no more than two or three minutes' direct noon sun on the display of my G70. It went totally black, and needed taking inside and cooling down in A/C before it (thank God!) came back right as rain...
