Blend two colors, using a hard edge, in an arc.

Hello everyone, I hope all of you have been well.  Lately, I've been experimenting with designing backgrounds/wallpapers and need to know how to blend? two colors together in an arc shape.

To better describe what I have weakly explained, here:

Example



is an example of what I hope to be able to achieve with Gimp.  This type of meeting of two colors, green and white in this case, is seen everywhere now and I would like to reproduce it.

Maybe something like this

A shape layer with an alpha lock
The gradient tool with a spiral shape. 
This is the awkward one, juggle the end points to get just part of the spiral showing.
Blend colour space CIE Lab
Gradient center point with Blending - Curved and adjusted to suit

Thanks, Rich.

I made a rough draft of what you suggested and it's what I needed. It wasn't so much even the spirals but, the shape meeting another color and you gave me the basic concept of how to do it.  I'll go back and read your instructions more closely and make things look better on a background I make.

Just build it up with layers.
