MATLAB: How to get RGB values from x,y coordinates

rgb color space

I have the x,y coordinates of different colors (they are not coordinates of an image, just the hue coordinates) in CIE color space and I want to convert them into RGB values. i have for example x= 0.5732 and y= 0.2463. How can I convert these coordinates to RGB?

Note: Make sure that you pick the correct whitepoint. Generally there will not be much difference between D65, A and an ideal 6500K black body radiator, but sometimes it matters for your result.

Hi Loong,

XYZ is the tristimulus values and not the coordinate system, since the color space is varied from XYZ to RGB.

You can directly provide a XYZ colorspace image of size m-by-n-by-3 and you can convert to RGB image.

To convert RGB to XYZ, use rgb2xyz function.

For more details about different color spaces and usages, look at this page.

Hope this helps.

Regards,

Sriram
