What is the meaning of まっちろけ?


> まっちろけなお弁当になっちゃった。 (context: it's lunch)

or

> どれも、なんかまっちろけでさ。 (context: scene of an accident)

Does it have something to do with 真っ白, masshiro?  
I think it may be some sort of obscure slang I don't know about, because I
can't find any information on the internet and I don't see how pure white
(masshiro) could apply to either of the examples.




「まっちろけ」 is indeed a colloquial and/or jocular way of saying 「真{ま}っ白{しろ}」,
which means "pure/all white".

「まっちろけなお弁当{べんとう}」 would refer to a bento consisting of rice (which is white)
and other things that are mostly very light-colored. Upon hearing that phrase,
most Japanese-speakers would think of a visually unappetizing bento.

Finally, without more context or an explanation of the situation, I could not
tell what 「どれも、なんかまっちろけでさ。」 might mean. It could mean that the speaker has a
blurred memory of the accident, but I really should not be speculating. We do
say 「頭の中が真っ白になる」 to mean "My mind went blank."
