@gobstopp , This is typical oxidation of cannabinoids to quinones. There are important differences in the colors reported. Some folks call everything “purple”, but there are several shades, indicating different compounds.
On my phone (Samsung Note 10+), at least, here are some emoji to represent color differences:
These are shades of the purple (violet) color seen in some CBD quinone products 
, most often caused by oxidation in the presence of alkali.
These mauve shades 
are often mistaken for “purple”, although they are forms of red, indicating THC quinones from similar alkaline oxidizing conditions. Sometimes they are mixed with true purple 
, indicating both CBD & THC quinones from said conditions.
These are shades of more pure red 
or reddish pink:anatomical_heart:
often seen from higher concentrations of THC quinone products that have oxidized in air at neutral or with acid present.
These are pink to peach shades 
which happen sometimes in attempts to make “water clear” or intentional “rosé”, from pure THC quinone in highly colorless, neutral products.
Reddish brown shades 
happen when CBD and/or THC quinones & chlorophyll are together.
Crude brown shades 
and high quality crude tan colors:maté:
are from xanthophyll yellows, carotenoid oranges, chlorophyll & other pigments, cannabino-quinoids and terpene oxides, all together.
These are “yellow” amber shades:orange_heart:
or dark “red” amber 
which are carotenoids and/or yellow+red:pill:, from the xanthophylls & quinones, respectively.
The usual:fire:yellow/gold shades 
come from xanthophyll yellow pigments.
These are grayish shades seen in some water white products 
that have not oxidized… Too much darkness can indicate black solid particulate impurities, like charcoal, but it may also be a trick of the light refraction through different transparent solids like glass & resin.
There are even rare occurrences of green & blue during processes 
, caused by unusual refractory characteristics of mixtures, terpene decomposition products, polymorphism in crystal structures, and other bizarre phenomena.
Unicorns🦄 & rainbows🌈, folks!
EDIT: Yeah, the forum replacement emoji are off-colored, dang it.
