I would filter by the red color plane.
See below:
myImage = imread('too-much-red-meat101.jpg');
rPlane = myImage(:,:,1) - 0.5*(myImage(:,:,2)) - 0.5*(myImage(:,:,3));
red = rPlane > 100 ;
white = rPlane < 5;
pink = rPlane > 5  & rPlane < 100;
figure
imshow(red)
figure
imshow(white)
figure
imshow(pink)
I tried this on a picture from google images and it seemed to work well. You probably need to pick different criteria for red, white, pink, and black. My photo only had red, white and pink.
