You aren't using enough colors to span your color gamut. Three colors is simply not enough. People often use 24 because they use the industry standard x-rite Color Checker Chart. If you use only three (white, blue, and orange), then there are regions of the gamut that will get mapped to crazy, incorrect colors, as you are observing. You need to specify more standard/reference colors.

Color correction does not change the shape of anything. What you are seeing are jpeg compression artifacts. You saved the image with a very very low quality factor.
