Is it possible to automatically replace colors in a gradient?

Question

Design

There is such a gradient in the current style of the site https://dropmefiles.com/aKCMS
It is necessary to redo the style, I replaced all colors in css, but is it possible to somehow automatically replace all shades from purple to green in such a picture?

Answer 1

Can. Animations or JavaScript.

Answer 2

If I understand correctly, you need a Hue shift. In Photoshop, Ctrl + U and move the top slider.

Answer 3

If the task is to match colors specifically through CSS, use the filter property.
