orderedcolors

Create a stacked bar chart containing four bars with five sections each.

y = [3 5 7 9 11; 
     2 5 6 8 10; 
     4 6 8 10 12; 
     3 5 7 9 11];

bar(y,"stacked")
legend(Location="northeastoutside")

Change the colors of the chart to the last five colors of the 12-color gem12 palette. Get the RGB triplets of the gem12 palette and store them in matrix C. Change the colors of the chart by calling the colororder function and specifying the last five rows of the matrix.

C = orderedcolors("gem12");
colororder(C(8:12,:))

You can get the RGB triplets of a palette and use them to customize other aspects of your visualization. In this case, match the color of the figure to one of the palette colors.

Create a scatter plot with the reef color palette.

f = figure;
scatter(rand(10,10),rand(10,10),"filled")
colororder("reef")

Get the RGB triplets of the color palette.

C = orderedcolors("reef")

C = 6×3

    0.8660    0.3290         0
    0.3290    0.7130    1.0000
    0.0660    0.4430    0.7450
    0.9960    0.5640    0.2620
    0.4540    0.9210    0.8540
         0    0.6390    0.6390

Change the color of the figure to the fifth color in the reef palette.

f.Color = C(5,:);
