I am making a low-poly fox and wanted to make it very bright orange like this one

But I couldn't get this colour from just from shaders, so I tried to brighten it up. The effect was quite good but I also get a lot of red colour on some of my mesh.

How can I get a bright orange colour and get rid of that red parts?
