I always thought DIB was less purple.. until I saw one the other day. Cloudy and wet.. conditions that make Kona purple. The DIB was just as purple.. but it was a brighter shade of purple.
Pretty much every shade of dark blue will have purplish hues in the right conditions.
One thing ive noticed with KB... under LED lights (have some in the garage).. Kona is BRILLIANT! Probably has to do with the fact that white LEDs are slightly bluish.
