Hi! Its your code. Sorry, I should have said.

This conversation came out of the discussion: [Color to grayscale algorithm](https://discourse.processing.org/t/color-to-grayscale-algorithm/45171)

The widely used algorithms mentioned have floats for RGB values. For example,  
`Luminance = 0.2126 * Red + 0.7152 * Green + 0.0722 * Blue`

I’ll read the Medium articles with great interest. Thank you!
