You can't really judge the colors by looking at pics on a computer screen. As long as they're made by Floquil/Polly Scale, then those are the correct colors.
For info, the color numbers for Reefer Yellow are F414122 (Polly Scale) and F110031 (Floquil). The ATSF Yellow number is F110178 (Floquil) and I couldn't find the number for the Polly Scale version. . . all my paints are packed up right now.
