Page Camera and Blue Handwritten Text

Idea

Xperia M2, EN 6.3.3.1

 

No problem when writing with black ink (only a bit faded)

More problems when writing with red ink.

Big problems when writing with blue ink, the page is very (very) faded.

 

It's only a problem of mine? Anybody else?

 

Cheers.

Red much improved; blue very good results.

Thanks EN (and all the people behind it)

I think this is why forms often say 'complete in black ink' and special effects use blue screens.  Can't be bothered to google the science,  but electronic cameras and the colour blue aren't a good match...

 

IMHO I believe  Black ink has the biggest contrast on a white paper, so it's the easiest to detect and they don't have to say "you can only use elettric blue, dark red, brown, ..." ... best results with less words).

 

Special effects: I knew blue is the farthest color from our skin tone.

 

BTW something changed with "EN Post-It Camera" (https://discussion.evernote.com/topic/46050-3m-post-it-notes-and-evernote-for-android/?p=255935): light yellow post-it maybe are not detected as Post-It, but at least the text isn't turned white anymore..

Cheers. G
