Dashboard color scheme change

For a client I am looking for a color scheme change, they wanna use as much of the original website, maxinu.io but are open to any suggestions.

Needs to look, warm, inviting, and professional

I added the images how it looks not which is pretty bad, The change we will make ours self, as long if you document well which colors where with color code

Website: maxinu.io
Dashboard: app.maxinu.io
