In this exercise, the original idea was to transform the red color of the background into turquoise, but during the process complications appeared and, because of the time it took to solve them, I stayed with pink.
The reason was that pink is very close to red on the color wheel, while turquoise is almost at the opposite end. And when moving the hue, I had to constantly isolate the skin. Besides that, the qualifiers don't always pick up and isolate every pixel correctly. On the other hand, if I removed the red tone to level it with the green (G) and the blue (B), the image lost a large part of its luminosity. Therefore, I decided to take advantage of the fact that the original footage was red and change it to a similar color.
The lesson I learned is that, although it would have been possible for me to change the color to turquoise (even if it meant spending more time), it will be more efficient if the final look being sought is compatible with the material that has been shot. Because in color grading you can modify, shift and refine, but you can't expect to turn it into any color you want.
