My notes with the highlighting do seem to render well in my Galaxy Note phone.
#Different highlight colors in word windows
Windows apps such as Word, Excel, LibreOffice Writer and even the minimalist Wordpad Many applications on many different platforms have a choice of highlight colours, either as a list of predefined colours (less useful), or a fully configurable colour chooser.
I understand that some people prefer muted colours, whilst others (such as myself) prefer much brighter fluorescent colours for highlighting, so I would suggest that the solution would be to allow users to choose.
The poor highlight contrast is especially apparent on web-clipped pages which may contain other coloured elements such as images. I think that the word "highlight" indicates what the function should do, however the pale yellow in the Evernote Windows app is barely visible, so it hardly highlights at all.
