Why does the computer cursor looks like a rainbow when you slowly hover it over a letter?

Question

I noticed that if you slowly hover your cursor over the letters in ms-word, it creates a rainbow like colors at the intersecting point between cursor and the letter. It works best on letters with diagonal lines like ‘W’ or ‘V’. Why does this happen?

Probnalt something to do with how the monitor handles the way each pixel handles the image being displayed.

Assuming your cursor is white and the background is white, the cursor border over the text is probably bit much for each pixel to display the colours correctly, so there’s some bleed between what each pixel is doing.

Someone will probably have a better explanation
