Medical GUI - Change hemorrhage text colors

[severgun]

When merged this pull request will:

• Change hemorrhage text color from always red to yellow-red grade.

There was feature request to change Lost some blood text color from red to white. I think yellow is better to show that there is some loss but not so "screaming" as red.

Or should I take colors from #8350 ?
For example 3, 5, 7, 9

Using colors from #8350 sounds like a good idea to me. But I don't think it's that important, how is the visibility of this way vs. using #8350 colors? Different places might prefer slightly different shades for good visibility.
