Why does the color on my objects look so diffrent from the one on my material?

I have tried putting the lighting source on other places and that dose n’t help.
How do i get the same color that is on my material to show up?

The level you are using is the cause of your problem. The PostProcess and the DirectionalLight are set to be very dark. PostProcess => ExposureCompensation is at 0 (default 1) and DirecetionalLight has an Intensity of 2,75 (default 10). So if you create a new level via FILE => NEW LEVEL => BASIC and place your meshes there they will look completly different.
