I am having trouble with BMP to TMX. I get an error saying that I have incorrect colors but the RGB value in the error, the .bmp, and the guide are all matching. The RGB values I am having trouble with are RGB=0,138,255 and RGB=117,117,47. The error says that I have many pixels with unknown colors (x,y=278,158 x,y=279,158 x,y=280,158...) but only two unknown RGB values.
