2b. consider the hyperspectral data from the Ishihara plates in the additional accompanying spreadsheet. This includes two spectra per plate, one for the dots that make up the numeral (labeled Foreground) and the other for the dots that make up the background. For each plate, calculate the LMS-numbers for each dot spectrum

2c. Now that you have these LMS-numbers, you can use them to talk about the similarity between these colors in cone space. Calculate the distance between the foreground and background dots in each plate using the LMS-numbers. Turn in the distance that you calculate for each pair and also tell me which pair appears to be the most similar based on this calculation.
