Change color of gradient that follows mouse

Hello, I'm using the "Amal" template that came with a mouse-follow effect that I really like, but I do not know how to change the color. Attached is a picture. I would like to be able to change the color with hex codes. Thanks so much!

As far as I'm aware this is not a standard feature on Squarespace template, so was probably installed by someone. I would check in Code Injection and Custom CSS to find where the colour is set.
