Move the sliders until the colors in the right column match the colors in the left column. The further left you move the slider, the darker the right color becomes. Click OK when you think you've positioned the sliders properly. If you don't have them just right, adjust the sliders and click Ok again. You get 10 clicks to get it right. If you fail, you'll be debuffed and have to wait 45 seconds until the buff expires before you can try it again. You will need a Biological Yeast Dispenser from Halden Wes (a Corellia Times reporter) for each serie of attempts.
