Coloured equation in Impress

Hello! Is there a way to choose some colour for the equation in Impress instead of the default black one?

There is a color statement in Math that can be combined with a limited palette (RGB+CMYK+white) to set the hue of elements. The basic form is:

color <keyword> { math element }

Valid <keyword> entries appear to be: red, green, blue, cyan, magenta, yellow, black, white. For example:

color red {sum from{color magenta {i=1}} to{color cyan{100}} color blue {i.}}

Thanks a lot! That is exactly what I needed. However, I can see that the red, green and blue colors are dark. Is there a way to apply the light colors?

The only valid hues (keywords) are: red, green, blue, cyan, magenta, yellow, black, white.
