Dark Matters

When we read books, the letters on the page are usually printed in black colour.
Our eyes sensed light. So as we look at a page, light reflected from the page into our eyes.
As black colour appear black because the black ink absorbed all the light it is the letter's silhouette that we see as the alphabets making up the words.
Interesting that it is the thing that we can't see that means a lot of us.
