Understanding fancy colors

[echelon6]

So there's a fancy scale, I'm trying to understand it both from a pricing and beauty perspectives.

there's light, fancy, intense, vivid, dark, deep - but from photos on various websites I can see the Deep and Dark ones are just darkened of the same hue. If I want only max hue without any brightening or darkening, which grade do I go for? and separately, which grade commands the highest prices, all else equal?

Intense or vivid. For lab diamonds, ATM the prices seem to be high for deep or dark because there are fewer available on customer-facing platforms.

IMO for beauty it’s somewhere between fancy intense and fancy vivid. The color isn’t quite saturated enough below fancy intense, and visible fire starts taking a hit above fancy vivid.

Great question!!
Lab Diamonds do offer new possibilities. For example, HPHT, or irradiation - both are shunned by Natural FCD collectors.....with lab grown, buyers are not concerned
But to the crux of your question.
It's the wild west out there.
A miniscule percentage of FC lab D's have GIA reports.
IGI is not consistent with colors.
Colorless color grading is relatively simple.
It would not be realistic to expect them to be able to match GIA consistency on FCD's
Even GIA's grades are pretty darn wide- a very light Fancy Intense is MUCH lighter than the most saturated Intense.
The most saturated intenses are more saturated than the lightest stones graded Vivid yellow. It's not a precise science.
As far as which are more beautiful...of course that's a question of taste.
Light yellows are much rarer than deeper yellows in lab stones.
So prices might be topsy turvy compared to natural diamonds.

Lab diamonds live by different rules in general.
J's are very rare in Labs too- you'll find 100 D-E-F's compared to one J...
IN the case of a properly graded Fancy LIght Yellow versus Vivid Yellow, or a J Lab compared to a D, which is worth more?
