Purple is the colour of vital power. <ref>http://incarnateword.in/cwsa/30/colours#p9</ref>

Both [purple and crimson] are vital lights, but when seen above they represent the original forces of which the vital are the derivations. <ref>http://incarnateword.in/cwsa/30/colours#p88</ref>

There is a characteristic colour of mind, yellow, of the psychic, pink or pale rose, of the vital, purple; but these are colours corresponding to the forces of mind, psychic, vital—they are not the colours of the beings. Also other colours can play, e.g. in the vital, green and deep red as well as purple and there are other colours for the hostile vital forces. <ref>http://incarnateword.in/cwsa/30/colours#p6</ref>

There are different Krishna lights—pale diamond blue, lavender blue, deep blue etc. It depends on the plane in which it manifests. <ref> http://incarnateword.in/cwsa/30/colours#p41</ref>

Diamond blue is Krishna's light in the overmind—lavender blue in intuitive mind.<ref>http://incarnateword.in/cwsa/30/colours#p42</ref>

There is the whitish moonlight blue of Krishna's light—lavender blue of devotion, deep blue of the physical mind, sapphire blue of the higher mind and many others. <ref>http://incarnateword.in/cwsa/30/colours#p43</ref>

"Violet" is the colour of benevolence or compassion, but also more vividly of the Divine Grace—represented in the vision as flowing from the heights of the spiritual consciousness down on the earth. The golden cup is I suppose the Truth consciousness. <ref>http://incarnateword.in/cwsa/30/colours#p48</ref>

Violet is indeed the colour or light of Divine Compassion, so also of Krishna's grace. <ref>http://incarnateword.in/cwsa/30/colours#p49</ref>
