Body: <p>I was wondering if the <a href="https://en.wikipedia.org/wiki/Fr%C3%A9chet_inception_distance" rel="nofollow noreferrer">Frechet inception distance</a>
  for two colored datasets would be the same than the FID calculated for the same datasets converted to grayscale.</p>
  <p>I know that it depends on the feature extraction, which is the Inception network. And that is the question, I don't fully understand the role of color in CNNs. I thought that all color information is lost in the feature extraction, and in this case I grayscale and colored datasets would produce the same FID. But I am not sure about that.</p>

  I was wondering if the [Frechet inception distance](https://en.wikipedia.org/wiki/Fr%C3%A9chet_inception_distance)
  for two colored datasets would be the same than the FID calculated for the same datasets converted to grayscale.
  
  I know that it depends on the feature extraction, which is the Inception network. And that is the question, I don't fully understand the role of color in CNNs. I thought that all color information is lost in the feature extraction, and in this case I grayscale and colored datasets would produce the same FID. But I am not sure about that.
