The ability to perform wavelength to RGB transformations is not available in Image Processing Toolbox.
To work around this issue in MATLAB 7.0 (R14) or later versions, you can use 2 files that were uploaded to MATLAB Central (you will still need the Image Processing Toolbox to use them):
1. spectrumRGB - Converts spectral wavelengths to RGB values.
2. colorMatchFcn - Raw data for various color matching functions.
These files can be found by searching for the keyword, "spectrumRGB," at the following URL:
An example of using these files is:
sRGB = spectrumRGB(380:780);
figure; imshow(repmat(sRGB, [10 1 1]))
Note that MathWorks does not guarantee or warrant the use or content of these submissions. Any questions, issues, or complaints should be directed to the contributing author.
There are other applications that perform this transformation. You can use the tool found in:
The code used to generate the colors is based on the work of Dan Bruton.
