Using hue/saturation layer cannot change color from green to yellow

[JohnnyAir]

This train was originally all white.  I went through the selection process to change it to a color.  I chose green but now I want yellow.

I tried using a hue/saturation adjustment layer but the slider doesn't want to offer me a yellow.

Any thought on this please?

Could you post a screen shot of the H/S Prpoerties panel? This works for me:

Here is a screen recording of my experience.  I don't think that the recording records my cursor but after the adjustment layer is created I select the green on the loco on the train.

This is a very common misunderstanding about how color works.

Every color has an inherent brightness at maximum saturation. Yellow is inherently very bright, purple is inherently very dark.

Digital image editing separates these components. You do get yellow! You just get a dark and desaturated yellow, which we perceive as "olive". It has been pushed out of its native saturation/brightness. That's how a dark yellow looks.

If you want to see this even more clearly demostrated, try to do it in Lab, which separates even more strictly between these components.

Thank you.
