To follow-up on our conversation about category schemes...
Here are a couple of examples of what I would like to explore.
Is there a better way to organize some of the schemes to support better color differentiation for maps with fewer categories and/or should we reconsider the default?
For example, a map with 3 categories, using Prism
:
Prism's current color order:
Would this be better? (Just as an example, haven't tested!)
OR
Should we default to another color scheme for category maps?
For example, the same three categories with Vivid:
Do we need to fine-tune any of the category schemes?
For example, do any of the colors in these schemes need to be better balanced or modified at an individual level? Are some colors in the schemes to close to one another? Do some have more saturation than others, etc?
Those are two questions to start with!
Let me know if you have any questions!
thanks! mamata
Vivid and Bold colors look like they are more easily distinguished from each other & Voyager.
I tested at a variety of zooms, including ones where the most Voyager colors were visible
2 Categories:
5 Categories:
Current:
5 Categories:
If Prism is re-ordered like this, the first 4 colors are a mini perceptual sequence: one category one doesn't stand out too much more than the others but they are still easier to distinguish from each other than current, u agree?:
5 Categories:
Or how about this (same idea w/1st few colors = one doesn't visibly stand out more than the other categories)?
5 Categories:
Current:
5 Categories:
How about this order instead against Voyager basemap, just putting yellow last?

Here are the adjusted palettes re-ordered light/dark (mostly, some light/dark swatches I switched for max contrast on the map):

I also did another light/dark re-order w/adjusted palettes, but again with some switches:
Goals for @ least first 2 swatches
Here are the original palette colors, re-ordered light/dark:
For comparison here are the original colors in original order:
Both sets are in here:
Here are the 2 & 3 category comparisons, including re-ordered Prism adjusted colors:
Here are the hex color schemes:
@ztephm thanks so much for going through this exercise!
There are some other tests I need to do with CARTO VL and category schemes. Once I wrap my head around that better, I'll walk you through it.
But I will use your modified schemes for that testing.
for example, 2 color version of Prism wouldn't be purple to blue it would be purple to yellow (basically, working in complementary, split complementary, etc.)
