In my picture this week, there is a bit of a red tint that I could not get rid of - my apologies in advance!
Here is my first example, I believe this would be an L-I mutation because the leaf surface lacking in chlorophyll is only on the outside edge of the leaf. (This could also be an example of L-III mutation because of the slight mottling throughout the leaf, although because the second leaf beneath my example does not show this, I will stick to L-I as my guess...)

Here is an example of an L-III mutation. This leaf is mostly lacking chlorophyll along the vascular structures, but this deficiency also presents itself in a more subdued way throughout the leaf.

I'll agree with LI on the first image, but the second image I'm not sure. LIII is a good guess, but it might be due to something called "non pattern variegation" that is controlled by a nuclear gene and isn't the result of a chimera.
