Hi @Turius,

There might be some cultural differences at play here, because I would think that most people (here in the Netherlands) would associate red with negative and blue with positive - could that be the case?

Kind regards,
Johnny

Hi @JohnnyDoorn,

Thank you for taking a look into this. It might be a cultural difference, but the native R function heatmap() also has an inverted color scheme in comparison to Jasp.

I guess that the Jasp code has a custom color scheme hard coded in? Perhaps different colorschemes could be chosen for heatmap, similarly than what currently coded for the "Descriptive" module?

I would also vote for a dropdown to be able to change the color scheme while sticking to the current one as default. This must clearly be a cultural thing and we want to be inclusive here.
