Yes, I think you should add a Solid Color layer of light grey (roughly an average of the blanket colour) and mask it onto the blanket, then lower its opacity.
We'll talk more about the cast once you've finished the Channel Mixer class.
Regarding the blanket and tub .... I understand why you'd like to get rid of the tub, but what's wrong with the blanket?
This happens to all of us from time to time. Nobody knows why.
You'll just need to re-load your actions. I agree it's a hassle.
To be safe, can you do this for me?
Yeah, so maybe add this Channel Mixer layer:
R 0, 0, +140, +45
G 0, 0, +150, +20
B 0, 0, +55, -15
Then lower the layer opacity to your taste (I found I liked it at about 55%).
Hi @1234, I've moved your question into the "How to achieve a certain look or effect" section. Can you start by reading the Posting Guidelines, and browsing the images therein to see if your question has already been answered? If not, include a link to a style you admire here in your thread.
