I spent countless hours learning and writing JavaScript for a fillable PDF that calculated the rates of products, based on information entered into other fields in the same form, it also conditionally made certain fields required or hidden or made them visible again based on what was entered into a certain field or whether or not a checkbox was checked, and lots more. Then when my company needed the form moved into Adobe Sign, I learned that all of that work went out the window, because Adobe Sign did not support JavaScript and had it's own "language" of sorts that was more limited. You can still add some dynamic capabilities, such as field calculations and set some conditional relationships between fields, but it was much more difficult to add all of the features that we needed. I was still able to create something acceptable for my company, but now a few weeks away from launching our forms in this environment, I realized I needed to change the color of a checkbox, the most BASIC and cosmetic change. I was then told be Adobe Support that I cannot change the field color in Adobe Sign, and I would have to do so in Adobe Acrobat then re-upload the PDF and create a new Adobe Sign template. This would undo ALL of the aforementioned work I did writing the formulas and calculations, and setting the conditional relationships between fields, that I did in the Adobe Sign environment - JUST to change the color of a checkbox! If Adobe Sign can support the capability to add dynamic fields and relationships between fields, surely they can offer the capability to change the color of a field.
