(White tends to crack easily and without warning, for example; most other colors will at least warn you.)

I've never had this problem with ABS. Could it be a function of dye in the PLA changing the melting point? ABS seems to melt pretty much the same no matter the color. (Disclaimer: only used Makerbot supplied stuff on my own printer, work used 3d something or rather as their source, no major problems there either)
