how can i obtain a .pdf of the pixel c user's manual

[AC Question]

went online, typed the query as many ways as possible but only got the spam websites that require accepting their app first in order to get user's manual. went to google help and received worse--got circular responses that seemed to be avoiding the request. just looking to have a .pdf version of the user's manual to keep on the pixel c.
thanks much!

Well, I found the solution after a good sleep.
I went into setting>accessibility>VISION>then scroll to the BOTTOM, and found NEGATIVE COLOUR. toggle it ON and OFF.
My headache is now gone!!!!
