- I have a question which I hope is not too basic, are there colours
- which can be represented in the true HSV cone which cannot be represented
- in the standard RGB cube? The text which I am reading tells me that the
- HSV cone is approximated to a hexagonal cone, is this just to make HSV
- and RGB strictly eqivalent?
- To my mind the HSV model is far easier to navigate within, but
- if the hardware or OS approximate your colour choice to a value within
- the HSVhexcone/RGB model when you choose a colour on the edge of the
- HSVtruecone your work will not be as you desired.
-
- It is my hope that these questions are pertinent and sensible.
