1.- Separate the components
A=imread('image_segmentation.jpg')
Ar=A(:,:,1);Ag=A(:,:,2);Ab=A(:,:,3)
2.- Apply the BW functions you show in the question to each primary colour
3.- Find the intersection pixels of the results found in the 3 layers

It looks like someone has already segmented it. The image started out as gray scale and then somehow segmented it and produced a pseudocolored version of it.
I'm not sure what you want to find here. You can see from the color gamut below that there are not well clustered colors. Everything is kind of blended.
As you rotate that gamut around, you get some very strange looking shapes, like "sheets" in the RGB Gamut space.
And here is what it looks like if you look straight down the V axis in HSV color space:
What color(s) do you want to find?
