dimmer switch

Happy New Year, I need a little help, I’m replacing the original dimmer switch on my console which has 3 wires, (red, black and blue) with a new dimmer switch that only comes with two wires (red and white). Is there a way to wire a two wire switch to three wires? Or do I need a different switch?

Have tried unsuccessfully to replace the rocker switch that controls the main cabin light fixture (halogen bulb) with 2 different dimmer switches. Can this light be controlled by a dimmer and if so how? Light works off battery, generator and shore power.
