As long as you like it, that's all that really matters.
Originally the bodies had a zinc chromate coating that gave them a grayish / silverish hue.
The bases were painted gloss black. Very thin paint to simply keep corrosion away for a short time.
Photo attached is a NOS carburetor (1939 / 40) and even though the photo is not in color, it's quite easy to discern the fact the body was "silverish" and the base gloss black.
After WWII the bodies had more of a golden hue, no doubt due to some chemical changes. However, only a slight tint of gold, nothing like what you have there.
