Create a hue mask in photoshop

Question

I would like to apply some adjustments only on a given hue range, i.e. create a hue mask.

What I have tried is to create a hue mask. I have done some tries, for example I use saturation ajustement layer, changing luminosity and saturation of the different colors, and then use channel mixer or saturation mask. None of the above mothds works for me, especially because I get some artifacts and chunks, which are not visible in the original image.

I have also tried select > color range but it creates some harsh transitions on object contours.

Photoshop has an option to convert an image to HSB/HSL under Filter->Other->HSB/HSL.

Given the following image:

Converting it results in the following hue channel (you'll find it under Channels->Red):

This can then be edited into a mask which can be applied to a layer:

Depending on the original image, more or less fine tuning might be required.
