Description of Bug: When attempting to dye a rug dark blue and copper, I received a different rug sprite as the result.  I already own a rug that I previously dyed dark blue and copper, which has a different sprite.
Reproduction Steps:

1.  Have an undyed rug, dark blue dye, and copper dye.
2.  Drag the dark blue dye onto the rug.
3.  Receive a rug in the dark blue + undyed color scheme, and an empty bowl. (I didn't screenshot this because it was expected behavior from my perspective)
4. Ctrl + drag the copper dye onto the rug.
5. Receive a rug that appears to be copper and brown (I'm really bad at telling this stuff by eyesight) and an empty bowl

Fixed.
