in this overload :

void HighlightOutput::Put(int count, const HlStyle& ink, const HlStyle& paper)
{
	Set(pos, count, ink);
	SetPaper(pos, count, paper.color);
	pos += count;
}

To simplify the use, the third parameter(const HlStyle& paper) can be just a color:

void HighlightOutput::Put(int count, const HlStyle& ink, const Color paper)
{
	Set(pos, count, ink);
	SetPaper(pos, count, paper);
	pos += count;
}

with this overload, instead of

HlStyle paper;
paper.color = LtYellow();
Put(5, ink, paper);

i can call it like:

Put(5, ink, LtYellow());
