When you select an object, down to the bottom of the inspector you will find the materials.
Highlighted in the red box is the ‘Main Color’ click on the box and a color pallet will show up, just select the color you want.
However the material you are using will be coloured so either find a suitable on or remove it, also shades make the colors look different.
