The Nexus Tritium wallet will allow for modifications to the background image and colors. @Kendal Cormany created a Matrix theme with a scrolling background, and I was able to install it in about 2 minutes. It is easy to create your own as well. I could have done this myself with no programming knowledge in about 15 minutes. I posted the directions to do this at the bottom of this post if you want to add it yourself.

When I asked if modules would be available at Tritium release, such as adding a clock or prices of other coins, the answer was…

It is still being worked on, there is a LOT to do to make sure that its good, we don’t want to have to put out updates and everyone has to rework their module. but it will be in version 1 and we have made huge strides on getting that to to completion

enabling custom theme modules could raise some security concerns, for example malicious code in a theme could attempt to hide the real addresses in your address book and show the attacker’s addresses instead so you would send money to the attacker

so it must be handled carefully and it would take some time

but I already have some solutions in mind, so don’t worry, custom themes will come, maybe the at same time with the module store, or lag behind a little bit

Installing the Matrix Scrolling theme to your Nexus Tritium wallet.

Download the gif below and save it on your computer.

2. Go to Settings -> Style and link to the gif using the Custom Wallpaper button

3. There are two ways to update the rest of the colors. You can paste the following code into Notepad and change it from txt to a json file. Then click the Import Custom Theme button at the bottom of the Style options and link to it…

{ “primary”: “#18e82f”, “defaultStyle”: “Custom”, “background”: “#272829”, “danger”: #8F240E”, “dangerAccent”: “#ffffff”, “foreground”: “#dedede”, “globeArchColor”: #04f219″, “globeColor”: “#163218”, “globePillarColor”: “#07f030”, “primaryAccent”: “#ffffff” }

Or, you can just click on each of the colors on the Settings screen and update each manually with the defined colors…

“primary color” “#18e82f”

“background color” “#272829”

“error color” “#8F240E”

“error color accent” “#ffffff”

“foreground color” “#dedede”

“globe arch color” “#04f219”

“globe color” “#163218”

“globe pillar color” “#07f030”

“primary color accent”: “#ffffff”

That’s it. Your background theme will change immediately.
