I am having the same issue. The thing is if you disable the neon glow, the text is in the right color. but if you do enable the glow.... the "glow itself is in the right color, but the text became all white. I am not too sure how it can be fixed. Let's hope the author will notice this

Some colors can be changed in the Extensions folder -> theme folder -> themes -> synthwave-color-theme.json may be it opens a way for you thanks.
