The thermostat has no idea what the color of a wire is. When the HVAC technician first installed the equipment and thermostat and ran the multi conductor cable between them, the individual color conductors were selected and attached to to terminals R, Y, W, G at the thermostat for example. And at the HVAC equipment, the same color used at the thermostat are used at the control board in the HVAC equipment.
for convenience, most thermostat cables, contain red, yellow, white, green, blue, and orange colored conductors.
If you would like some help, post the picture of the old thermostat base with the wires attached.
