Haven't got a D MK12, but you can use a color matching ap find the color closest to your needs spray the color on a white card let dry hold match card to your MK12 in outdoor light and see how they match. It may take you several applications of paint on the match card and also spray from different distances from the card as well, which can produce different hues of the same paint since you can't control the pressure if your using a can. If you go the airbrush route then you will be able to adjust the hue by air pressure and distance from sample card.
