Currently:
x1 is/appears to be of color/hue x2 as perceived/seen by x3 under conditions x4.
I presume x2 is a property (ka), and this is just a narrowing of ckaji; the property must say something about [how/which] light bounces off x1. So lo ka crino is a se skari, and probably (λx. x absorbs all light perfectly) also is, describing x1 as a perfect black body. But lo ka cmalu isn't.
I don't know if x3 should stay.
The x4 place can probably go.
