These are two pairs of shoes. I assume that without colour management a 
floating point sRGB representation will be clamped while converting to 
PNG. One solution would be to allow for a colour transform before 
clamping during the conversion from float to integer. The other is to 
allow for larger than sRGB, say ICC based. The later works even without
