[Rockhounds] Need help with Mineral ID

[Axel Emmermann]

Aha: the plot thickens !
 
That is precisely why fruit is the worse thing to compare fluorescent colors
by.
Personally I always try to describe colors like Mister Spock would do in
Strartrek.
For example: 
Main color: bleu - red - green -yellow 
Their compositions  purple - orange - brown - green - violet
Saturation: light (pink, beige, whitish, yellowish, etc....) or dark
(towards black)
Tint: bleu - red - green -yellow - purple - orange - brown - green

To describe a color you go like this: : main color or composed color -
saturation - tint.
If you follow that simple rule you'll never have to compare.

If I had to describe the fluorescence of say

It would go something like this:
Green, very unsaturated towards white,  no distinct tint.
OR
White, greenish tint.

Or this one:

Violet, very unsaturated with a bluish tint.
