Simple lighting without any effects

Hi everyone! Im looking a solution for creating an ambient light, like in Game Dev Tycoon game. I dont need any shadows and other lighting stuff. Just want to achieve a simple colors. How can I do that?

I`ve picked a screenshot - this is the ambient light I vant to achieve.

Thanks!

There’s no ambiant light here. Use unlit material or add some value to the emissive pin of your material

Thanks for reply. I’ve already found a solution, but that’s useful for me too.
