Great article!

Regarding the generated cat image:

Not quite; the eye color and heterochromia is followed only so-so.

The black-and-silver cat seems to have no heterochromia; eye color could be interpreted as silver though.

The white-and-gold cat _does_ have heterochromia. The colors can be interpreted as "white" and "gold", though I'd describe them as whitish-blue and orange. What's interesting about this is an adjustment of the instructions toward biologically more plausible eye colors in the cat which also has more natural fur colors.

The last cat's fur colors are so "implausible" that the model doesn't seem to have problems taking exactly those colors for the (heterochromatic) eyes too!
