Faux Finishing - need some ideas PLEASE

I need some ideas on how to tone down some pretty bright colors that I have painted by bedroom. I have a squash yellow that I rolled on then vertically ran a whisk broom thru, after that dried I horizontally whisked some rust accents on the yellow. I like it, and would LOVE it if it were not so bright. My idea was to go over the whole room with a white or very pale yellow paint or glaze then "comb" the overcoat so that it would tone down the colors but still let them come thru as more of an accent. Opinions? comments? ideas? open to anything right now.

Thanks :o

that would be my suggestion... apply a very diluted coat of white or pale yellow, and them "comb" or use a sponge to take out some of the coat and reveal the bright background behind it.
Do it in sessions little by little, so the paint will not dry while you are trying to comb it out. This will create an uneven effect.

You can also apply the white coat directly with the sponge, dabbing it around little by little. This way you can control the amount of paint you apply, how much of the background shows through, and the overall effect.
It takes a bit more time and some patience, but the result is worth.

If I am imagining it correctly, you might end up with an delightful "old world" texture on the wall, still with all the color you want but not so bright.

I would just rag the diluted white "wash" glaze over the top.

If you comb, which is a negative technique, you will be pressured to work quickly to avoid having the glaze set up on you.

Take you time, rag on the white wash as needed until you reach the desired result.
