Is there an upcoming Color Workshop?

Hi folks,

Tantek (CC'd) recently noticed & passed along a W3C questionnaire for a
Color Workshop, which seems to be surveying availability for some upcoming
color workshop event for various weeks in September 2021:
https://www.w3.org/2002/09/wbs/34257/ColorWorkshopDatesTimes/

The questionnaire is apparently open-for-answers until Aug 18th, i.e. open
for the next ~week, but unfortunately it doesn't have any info about the
event itself aside from the title "Color Workshop Dates and Times".

Does anyone have any more information about this Color Workshop in
september?  Tantek found https://www.w3.org/Graphics/Color/Workshop/cfp.html
, but that seems to about a separate event which is already complete or
mostly-complete.

Thanks,
~Daniel
