I love this species Lance!
Got it in one Bill- big bluish cast on my calibrated monitor too. I use the LAB colour space to correct casts, sharpen, reduce noise, saturate or desaturate etc.
The OP was running +4 on the A channel of LAB and a whopping -20 on the B. The B channel runs from Yellow (above zero, positive numbers) to blue (below zero, negative numbers), so there is the bluish cast staring you in the face. I converted image to LAB and pulled up or down the Curves on A and B to approximate A = 0, B = 0 on neutral tones (whites, greys). This is the result.
PS I can go into more detail on the method if needed.
