some strains are high cbd with no color, some very colorful strains have low cbd, some white strains are low in cbd and some are high same with thc. quality genetics are just that quality genetics. the color of a strain will have nothing to with rich cbd or thc levels IMHO. I would say the most important part is peak ripeness for harvest you like heavy hitters give it till all your trichoms are amber for a more pain killing sedative high wich is what I like for pain you want a more uplifting day time high take it down when they just start to go milky or cloudy. hope it helps man don't be misguided buy the beauty of color we all like colorful beauties but when it comes to med production some do some don't. talking about papavere somniferum's color can mean a great deal in strength but I have not found the same to be true with cannabis.
