Color changing text based on content

[GuruX]

I'm doing some digital signing for my work, and I need some help.

It's a digital sign for a boat. The sign tells people passing by, which cruises they can book.
The set up is a Raspberry Pi Zero W with a 3G modem attached. Pipresents displays jpeg images with the booking calendar.

My idea is a simple user interface where the booking office edits one or two text files over SSH and imagemagick generates the jpeg sign. The Raspberry will also mail the jpeg back to the office, so they can verify that it's correct.

Here's a mockup of the sign.

Getting the text into the image with annotate is an easy deal. I could just make multiple text files for each column of text that needs to be changed. But I wouldn't consider that user friendly.

What are your suggestions for making this user friendly and easy to use?

This is on Version: ImageMagick 6.8.9-9 Q16 arm

You could create an editable PDF using Adobe Acrobat. Then each time you change it and upload, have ImageMagick convert to jpg, if you need to do that.

Thanks fmw42.
Yeah, that is a good idea. It's pretty easy to edit and user friendly.
The only con seems to be that Adobe forms doesn't seem to make it possible for the user to change the color of the text. It's a preset. I'll see if I can find a workaround.
