You can't do it automatically as in a 1 click solution, but you should be able to do it using the mask tool, then possibly tracking the mask to follow movement and applying a colour correction filter to the inside of the mask such as the 3-way colour corrector. In the 3-way, you should then be able to use a qualifier to exclude lips and such to then only be working on the teeth.

It will be a bit of trial and error and futzing with the settings to get it right.

You can do it using the 3-Way Color Correction effect and its Color Range color picker. Masking will only be necessary if there are other things in the scene that have the same hue, saturation and luminance values. Otherwise the corrections will only be applied to the colors you defined. There is a Key Display button that will show you which portions of the image are affected by the corrections -- enable that, and then adjust the sliders to make sure the teeth, the whole teeth, and nothing but the teeth are affected.

To define the key, enable the hue, saturation and luminance checkboxes, select the Color Range radio button, and then click on part of the teeth to define the key. After the first click, you can shift-click to extend the color selection to a wider range of shades. In conjunction with the Key Display button you can confirm that the effect applies to the desired parts of the scene.

Next, drag the control points in the Black Balance, Gray Balance and White Balance controls to make the desired color corrections.

I suggested the masking because there are likely to be other things in the scene that will be effected like whites of the eyes or possibly clothing if the original colour is not too far off those. and using qualifiers to determine a key for the correction often requires making the key a little wider than a single colour and possibly even blurring it a bit to keep it from having a hard edge and being too noticeable. The mask will protect other areas of the frame from being effected without you noticing it.

Thank you very much, after making a mask, and using tracking, this Topic is solved. :)

I rather like to try out this method "3-Way Color Correction effect and its Color Range color picker" as well. :)

James,

The process described by both me and Thoff is identical with the exception of me saying to use a mask and apply the 3 say inside it. When I spoke of qualifiers, it is the colour or luma range picker that Thoff mentioned. Qualifier is just a more generic term used in colour correction processes.

Using the mask as the first step just protects other areas of the image from being effected by mistake and you not noticing it.
