K30 / K5 AWB color accuracy question

How good are the K30 / K5 / K5 II in having a good reproduction of color when used in AWB mode?

I am asking because I have a Sony A65 and it is not that good at getting good color accuracy when using AWB mode (using Tamron 18-270 PZD lens).   Brown dogs come out slightly bluish, white clouds in blue sky slightly pinkish, red rock formations are a bit greyish, etc.  Of course I know I can set a custom white balance using a grey card.  But on vacation with the kids, I just don't have time for that.   And as for post processing, well the point of the photograph was to show us what things looked like.   My Fuji XS-1 superzoom does a much better job accurately recreating the colors we actually saw when simply set to AWB mode.   Surely there must be a DSLR somewhere that does as well.  So I am hoping that maybe a Pentax camera is that DSLR. (I am planning for our upcoming vacations this summer.)  Any comments?
