Yes. A simple approach is to use a separate layer and a mask rather than relying only on the Guided Edit vignette.

Create a new layer, fill it with the color you want, and then use a vignette-style mask on that layer. The mask controls where the color shows, and the soft edges of the mask create the vignette effect. Because the color is on its own layer, you can change it easily later. You can also adjust the layer opacity to make the colored vignette stronger or more subtle.

In short: the easiest beginner-friendly method is a color-filled layer plus a vignette mask. That gives you any color you want and lets you control the transparency smoothly.

One community answer mentioned more advanced methods, but those are not necessary for a basic colored vignette.
