As far as i know, Variations was removed from photoshop cs6 standard/extended and photoshop cc on the mac side
(the windows versions still have the variations command)
You can use Levels in place of variations.
You helped me to start exploring other tools in the Image>Adjustments Menu. "Image>Adjustments>Color Balance…" seemed to help me get the results that "Image>Adjustments>Variations…" used to deliver. "Image>Adjustments>Photo Filter>Warming Filter (85)" also got me to where I wanted to be in desired adjustments. I used to get the results I wanted in brightness, contrast, mid-tone adjustment, and color balance buy using just Curves, Variations, and Hue/Saturation. Now I'll use "Color Balance…" and "Photo Filter>Warming Filter (85)" along with Curves, and Hue/Saturation. I also have learned to use "Levels" some more to get the same effect as Adjustments>Variations…" I always thought there were more technically precise adjustment tools to get the same effect as "Image>Adjustments>Variations…" Adobe dropping Variations in Photoshop CS6 Mac version forced me to learn better image adjustment approaches for pre press color correction and image warming. I feel confident now to make Photoshop CS6 my prime-time work tool and move the Photoshop CS4 launch icon off of my Mac OS app Dock. Thanks again, R_Kelly.
Before-&-after with Photohop-CS6 using Curves, Hue/Saturation, and Color Balance . . .
Let's see, you dulled the greens of the plants, the yellow of the shirt and the purple of the chair. The wall and the white shirt acquired a distinct and disturbing pinkish cast.
What is the reason you're showing this now?
Oh, now I see you deleted your images while I was still typing.
