code for color matlab

Hi all,

I am reading a paper and very impressive with the color that the authors used in the graphs.

So I would like to ask how to construct the color code for those colors? I knew that the color in Matlab is defined by [x y z] which relates to how much the green, red and blue contribute.

Thanks

1) Use software that has a color dropper so you can select the colored object and get its RGB values. Here's a simple, free, website where you can upload a photo, select the color, and it will return the RGB values. https://imagecolorpicker.com/

2) If the RGB values are not in decimal form, divide by 255. For example, if the RGB values are [56, 105, 137] then convert them to matlab's normalized values: rgb = [56, 105, 137] / 255;

3) set the color in your code: plot(x,y, 'color', rgb)
