How to add a color swatch/color picker in Display Form

I have a workflow that will query a parcel dataset by an attribute value (NBH) and my goal is to symbolize the result set by unique value (IMP_TYPE).  I have the majority of the workflow copmlete in that it will select the specific neighborhood (NBH), get the unique improvement types (IMP_TYPE) within that neighborhood, and will loop through each result looking at the IMP_TYPE field.  I want to be able to symbolize the graphics layer (featureSet) on this unique value and assign a specific color to each unique value, then set the renderer and update the graphics layer.  I then want to be able to display in a form the unique values and their associated assigned color.  For example, value R1 = Red, R2 = Yellow, etc...  Is there a way to show this in a display form like the image below?  Idealy I'd like the swatch to be a color picker but would settle for just the color swatch.  Any thoughts or help would be greatly appreciated.

  Here's something that just came to mind. It will only work if the number of colors is limited.

   

  Add a combobox to the displayform, and add the colors you want to it. Then, add this to the custom styles file (Resources\Styles\Custom\DEVICE.css) option:nth-child(1) { background-color: red; } option:nth-child(2) { background-color: green; } option:nth-child(3) { background-color: blue; }

   

  You will need to make the selectors a bit more specific, this example will work for any combobox/listbox on the page, maybe you could use the id of the SELECT tag, e.g. #formitem-avwfX2rt > option:nth-child(1) but I'm not sure if that's a static value.

  Clever move, Berend.  I'd like to add that you can use hexadecimal representations here in addition to the css named colors (https://www.w3schools.com/cssref/css_colors.asp) ie: option:nth-child(0) { background-color: #7D64C8; }

  So, if I understand you correctly, the entire 'row' of the combobox/listbox will be the color specified in the css file?  I suppose that would work but this would just be for visual purposes only, kind of like a legend.  I'm currently adding the unique values to a Markdown item in the form (image below).  Is there any way to add a color swatch next to the line item (next to 4.00 and 5.00)?

  I haven't found a way to use colors in a markdown item, but I do know that the Description for a Group item recognizes most html tags. You could for instance use a table where the background color for the first column (TD) is set.

  Hey Berend,

   

  Thanks for the input, I'll give that a try.
