ScannedMapDigitizer smd.create_mask giving black outputs

[AveryDurham]

I'm trying to run arcgis.learn code to digitize a scanned map. So far, no matter the parameters I set, the binary mask output is all blank with every pixel having a [0,0,0] RBG value. The zoneColors are the exact values for red that is found in the input image. The other three variables I don't know as much about so I expect the error is in there somewhere.

Here is my code: 

zoneColors = (234, 26, 26)

colorRange = 10

kSize = [3, 3]

kType = "rect"

smd.create_mask(color_list = zoneColors, color_delta = colorRange, kernel_size = kSize, kernel_type = kType, show_result = True)

Here is the output:

When I run the code with similar parameters to create the template image it seems to create a binary raster just fine.

Any idea on what I need to do to actually get a binary mask?

I'm using python 3.7.11 and running the code in Visual Studio.

EDIT: I found that what I needed was to have double brackets around the colors variable.

[[236, 24, 24]]
