Can't find colorblind friendly ramps in Map Viewer Beta

[OliverIshmael]

According to a variety of articles, ESRI have recently provided over 200 colour ramps that have been tested as being colorblind friendly - to ensure that the ramp shows detectable colour variation with the most common type of colour blindness.

When i use the Map Viewer Beta it only shows 4 options (and makes no reference to anything colorblind friendly):

I appreciate this could be 'Beta' related issue - but just wanted to know if anyone had any salient advice for me?

Hey Oliver,

I did a quick test with my own ArcGIS Online account and I was able to find a filter for colorblind friendly ramps.  This may sound very redundant but after selecting the "All Color Ramps" are you able to scroll down further?  When I do so I'm able to find that colorblind filter and I see quite a few options appear.

It seems that Colorblind friendly ramps are only available for numeric data fields e.g. Short Integer and Double but not String

Also Colorblind friendly ramps are only available when you select a Drawing Style = Counts & Amounts (Color).
