The color of the oils from the various flax samples, while primarily 
golden yellow, differed considerably in the depth of the shade, 
varying from a deep golden yellow bordering on brown to a very 
pale lemon yellow or straw color. Whether there is any existing 
relationship between the color and the quality of the oils can not be 
definitely stated, unless it is found that the color properties can be 
correlated with some of the more important physical and chemical 
properties.
