bug#6693: 24.0.50; font-lock-(builtin|doc) faces are *way* too close

See attached.  I'd say that three of the faces shown are quite close in
appearance: 

`font-lock-builtin-face' (":type", ":group")
`font-lock-doc-face'     (the doc strings)
`font-lock-keyword-face' ("defcustom")

But especially the first two of these are close.

The point was also that previously these faces were better distinguished -
`font-lock-builtin-face' was `Orchid', not `MediumOrchid4'.

Those same hex values are used on my system.  Those are the hex values
corresponding to the two named colors used: VioletRed4 and MediumOrchid4.
