You (as the frontend programmer) don't do that. Instead the user
sets the option that represents the scan mode as he likes.
Usually this option is named "mode" and is a string list with values
like "Color" or "Gray".

Keep in mind that this option needn't exist and even if it exists,
there may not be a color mode.
