Medical visualization often contain colors that highlight important information. When printing medical scoring boards in grayscale, the semantic information of colors is lost. Hence, visualizations relies on text-based information for the reader to comprehend images in grayscale. Common grayscale mapping methods do not preserve the special semantics of colors. In medical scoring boards, colors that are used are red for critical, yellow for warning, green for harmless, and blue for without any concerns. To overcome problem of information loss, we present PRECOSE, a method for the color to grayscale conversion for medical scoring boards, which enables to PREserve COlor SEmantics in a grayscale color space. With PRECOSE medical scoring boards do not longer have the need for textual features. They can be printed in grayscale without the loss of colors' semantics.
