Correcting Color Casts in Photoshop

1) duplicate the original layer, in this example a scenic with a strong red cast

2) Apply Filter>Blur>Average to get ...

 ... a layer of just one color - the color cast with RGB values of 123:108:118

 3) Invert the color layer ...

... to get the complementary (opposite) color with RGB values of 114:148:138

4) Blend Color mode

5) Change opacity to 10-40%

6) If it looks 'flat' add a bit of saturation.  As this looks ok to me, I did not add any saturation.   Compare the color cast removed version (this one) with the original in step 1 above.
