Is it possible to toggle between different qlik sense themes to make Apps more colorblind friendly?

We have a number of colorblind users of our Qlik applications so I want to make them more accessible. I am seeking the easiest way to be able to toggle between colors that are colorblind friendly v ones that are meaningful to non colorblind users. Anyone know the most efficient way to do this?

I found this post, but it appears this might not be the recommended way to do this. Additionally, I can only get it half working. No matter what I put after the '/' it always changes to the same theme.

any thoughts?

The theme URL parameter is indeed the way to handle this, the trick is to use the theme qextFilename in the URL.

For example, I have a custom theme I use called Arc theme. I wouldn't use /theme/Arc theme in the URL, though, I would instead use the theme's qextFilename value which is arc-theme. So /theme/arc-theme will work correctly.

To find the qextFilename value:

• Qlik Cloud: In the Management Console, go to the Themes section and then find the qextFilename value for the desired theme in the table:

• Qlik Sense Client Managed: From the QMC, go to the Extensions section, find the desired theme, export it, and then check the name of the qext file:
