How to vary symbol shape and color based on a non-numerical attributes

[ZoeAmerigian]

I have a layer of points that each have two attributes. I want Attribute 1 to control the symbol shape and Attribute 2 to control the symbol color, with any possible combination of the two. Both are inputted as Text datatypes for the moment. Attribute 1 has 3 domain values and Attribute 2 has 6 domain values.

To change the symbol shape based on Attribute 1, I changed the layer symbology to Unique Values and assigned a shape to each domain value of that attribute. But I cannot figure out how to make the symbol color change based on the other attribute. I tried assigning Unique Values based on two fields, but creating a symbol/color combination for all possible combinations of attributes is very cumbersome. I tried changing Attribute 2 to a numerical integer and using "Vary symbology based on color", but this feature appears to be for continuous numerical values and not discrete values.

How do I approach this?

I would keep a field as text and classify it according to Unique Values, figure out how you want to size the other field and then create a new field with the appropriate numbers to size from.

Eggs    |  Chicken  |  1

Eggs    |  Ostrich   |   5

Eggs    |  Duck      |   2

Beans  |  Beanstalk  |  2

Beans  |  Giant Beanstalk  |  10

To symbolise by these follow the workflow described here:

I did try this (varying by color, not size) but it is a little iffy working with discrete values instead of continuous ones. I made Attribute 2 a short integer datatype and used the Color option of "Vary symbology by attribute".

Then I made a discrete color scheme with 6 colors to match to the 6 domain values of the attribute. But when I do this, the color scheme breaks up the possible values into 3 "ranges" (see screenshot). I'm not sure why there are only 3, if I could create 6 ranges I could maybe map them to the 6 values, but I can't seem to figure out how to change the number of value ranges. Ideally I could simply map one color to one value and not have any ranges at all.

Below you can see the the 3 ranges on the left in the Contents panel the range sliders in the Symbology panel on the right.

It certainly could be done with Arcade expression, which is almost the same as any code language. Here is one of my example. Cheers!
