Christmas A uses the following OpenType features to set up to four different color layers.

- Small Caps / changing direction - Superscript/Superior (Trees) - Subscript/Inferior (Stars) - Numerator (Candles) - Denominator (Light, Bells)

Note: Due to the complexity of some parts of the font, some printers may have problems of rendering it smoothly. To avoid this problem you should always outline the font data for the final documents. On lower systems turn font antialiasing off for faster screen redrawings.
