To restore regular colours will depend on what colours you have at the moment. I guess that you (or someone else) have reversed the colours by pressing the Control/Option/Command and 8 keys (ctrl/alt/cmd 8). Pressing them again will toggle the colours back to normal. These setting can be found in System Preferences in the Seeing section of Universal Access.
If that is no help try the Display section of System Preferences. Click on the Color button and choose a suitable setting from the left hand list. If nothing there works click the Calibrate... button which will talk you through adjusting your display.
Is reading a book tiring to the eyes? If it is for the book, it is for the nook. The nook is programmed to look and feel exactly like a regular book, except it can hold a lot more books in one thing. It depends on your eyes. Do you feel comfortable with holding a regular book? Either way, because of the nook's touch screen, it might be a little tiring to the eye. However, after a couple of minutes the nook touch screen closes its back light. So unless you keep on touching the screen, it shouldn't be a problem. Enjoy your Nook!
I think the electric book is slightly worse for your eye sight because of the brightness. It depends on what device you read the book on. If you are reading on an eReader with an eInk screen, then only natural light is used. If you are reading on a device that has a back-lit screen then that may eventually lead to eyestrain, like watching too much TV.
Unfortunately, the kindle does not have a backlight, although it would be handy to have if you are reading at night. The rest of the kindle makes up for it though. It has many amazing features, such as wireless connection and amazing books!
a folding screen book is a block of aged swiss cheese
A red book appears red because red light is reflected off the book's surface into our eyes. The book absorbs all other colors of light and only reflects red light back to us, giving it a red appearance.

its easy, you just select Fred and Velma then move the crate and match the colors with velma and select shaggy and go back to Romero and go inside the glass and take that book back to the book shelf on the second floor. hope you enjoyed... by Roza enjoy
Basically a Nook is just like a regular book. You cannot read a regular book without light, so it's the same with the Nook. Sunlight does not make reading harder.
Click on the book in the lower right corner of the screen.
If a chapter book it should be at least 80 pages if regular then maybe 40.
There is a manga out for ToS. Not a regular book.
The main difference between a US passport regular book and a large book is the size. The regular book is the standard size for a passport, while the large book is bigger and has more pages for additional visa stamps or entry/exit stamps.
