Did anyone ever come across a sure-fire way to get this. I'm working on an iMac that has this exact same problem. Regardless of what I do with the Apple Color Picker (under the "Other" selection); any selection is very light. The individuals I'm working with have older eyes and it is barely perceptible with old and/or younger eyes.
iMac Line (2012 and Later)
If you have the Colour Picker set to Colour Wheel you move the slider at the bottom to lighten or darken the colour you choose.
You probably have your macs brightness set too high. From the factory the brightness is set far too high and the colour temperature of the screen is too blue.
System Preferences> Displays Turn the brightness down to about a third, your eyes will adjust.
System Preferences> Displays> Colour> Calibrate.
Before pressing the Calibrate button hold down the option/ alt key.
This will bring up the Calibration Assistant, turn on expert mode press Continue.
Follow the instructions in each panel.
At one point you will be asked to select the Gamma, I run my mac on 2.2.
Then you will be asked to select the colour temperature try 6500k again
your eyes will quickly adjust and things will look natural.
this is widely accepted as 'normal' I run at 5500k as I work in photography and
am colour matching to printed material.
Give the new profile a name.

Thanks, Eau ...
It did help significantly to create a new profile (followed your instructions). I was able to darken the highlighting. But it seemed to have a side-effect of altering the appearances of photos that were on the desktop of family members, etc. Thanks for posting your response!
