Change colors in Qlik using variables

In this video/post I describe two ways to dynamically change the colors of your visuals in Qlik Sense.

The first one is quite simple:
Qlik uses the RGB color scheme, so we can color the visuals by expression using the RGB() function. Inside the function it we use the variables to change the colors.
In the video I create three variables (one for each color – R for Red, G for Green and B for Blue), and set the values to be between 0 and 255.
With that we use a slider changing these variables, and in the charts we use the following expression to use the desired color: RGB ( $(R) , $(G) , $(B) ) – Use the Dollar sign + Parenthesis to call the variables.

The second way in the video is by using a “Color table”, in which we have rgb codes for a rank/number of options, and we call these codes as texts using variables and set analysis (for instance:

Only( {<Color={‘Red’},SortColor={‘1’}>} ColorCode) .

The Color table used in the example was this one:

Red1rgb(243, 207, 204)
Red2rgb(231, 158, 153)
Red3rgb(220, 110, 102)
Red4rgb(208, 61, 51)
Red5rgb(138, 4, 0)
Yellow1rgb(245, 236, 204)
Yellow2rgb(235, 217, 153)
Yellow3rgb(225, 199, 102)
Yellow4rgb(215, 180, 51)
Yellow5rgb(205, 161, 0)
Blue 1 rgb(204, 205, 243)
Blue 2 rgb(153, 154, 231)
Blue 3 rgb(51, 53, 208)
Blue 4 rgb(3, 6, 161)
Blue 5 rgb(0, 2, 115)

There are many other ways and possibilities, but I hope you find it useful.
