Once again, DO NOT give the answers away in this thread: send me the answers by PM only please.
Oh, and this time I won't contact others personally with confirmation of their answer: this time it'll be done publicly.
Here goes...
I'll give answers out next Saturday, so you all have a week to think about this one.

Here goes...
I heard the front doorbell ring while watching television one rainy Bank Holiday afternoon, and when I rushed down to open the door there was nothing there, except for this strange message on a small slip of paper with the ink partly smudged. It consisted of a sentence and a string of numerical values, with only the first few numbers clearly visible:
"In black and white, from shades of grey, to all colours and beyond."
0, 12, 11, 7, 9, 11, 12, ...
The rest of the numbers were smudged, but I could just about make out the next few on that sheet of paper. Although the rest of them were smudged beyond recognition, I managed to figure out what all values were.
Q1: Following the numbers given so far, what are the next three values in that sequence?
Q2: Having deduced the answer to the first question, what then are the next THIRTEEN values in the sequence after that?.
I'll give answers out next Saturday, so you all have a week to think about this one.
