Neomatrix scrolling text with esp8266 wifi control

Ive had some success with this project but have become stuck on adding the colour spectrum to the esp8266 webpage displayed.
Heres the link to the instructions.

I dont know how to “add the spectrum to the server so the sketch can access the files”.
Any direction would be gr8.

Hi Chris,

I took a look, its not too clear to me. Why don’t you try messaging dkomando via Github and ask?
