Conditional formatting, color scale

I have this situation:
4.ods (26.3 KB)
How can i make it so that the cells on the A column take the color from the B column?
Also, How to make it so that values equal to or greater than 1000 have all the same color?
LibreOffice 26.2.2.2 620(Build:2)
Thank you.

color_scale cannot be applied to other cells, but perhaps an old-fashioned CF scheme might do the trick for you

That doesn’t work with Color_Scale either.
But you’re welcome to create 10 or even 20 different cell styles and use the classic version (but you’ll have to do that yourself, my friend).

Found the answer for the second question: just put the first and last values in the conditional formatting, and not leave the generic min and max.
