White balance/color standards? Photographing accurate bloom color

[MateoinLosAngeles]

Can anyone recommend settings to accurately reflect color? I wonder if any standard has been set, in my view, the most honest would probably be setting the wb to 5000K and use matching artificial light. But otherwise I feel it’s easy to misrepresent color, especially for those flowers that are sort of “in between” (you know those oranges that borderline yellow, or those pinks that are almost purple)
