surprising how few 'true' colors there are in the garden.

Hi Jim,
I'm looking forward to the day when we'll get an RHS colour chart for
metallic colours. Crocosmia are literally impossible to describe properly
because of their chromoplasts, and Nerine sarniensis are another similar
difficult group for similar reasons; their saturation and the amount of
light they reflect.

I look forward to the day when someone invents a colour pen that you place
on the part of the flower you want to measure and it gives you an automatic
RGB level. Who knows, if made in China or Taiwan it would probably be
cheaper than the RHS Colour Chart.

And of course another invention that would be good is computer software that
would give you a scale grid that you could place over digital images, and
thus to make the taking of measurements easier. We could then take our pics
outside but then do all the recording much quicker, and inside in the cool
or the warm, depending on the time of the year.

Food for thought.

Best Wishes,
Dave (Plymouth)
