Increase saturation one color only?

Is it possible to increase the saturation of one color only in VSE?

i would use The Gimp
open the image and open the hue tool
then select the color you want to increase

In the ā€˜Nā€™ panel, go down to Modifiers and select the Hue Correct modifier. In the H,S,V buttons, make sure the S is selected. In the color chart, select whichever dot is closest to the color you want to change and raise it upward to increase Saturation.
