All microarray scans are tiff files and all tiff files are grayscale. The colors you see are generated by the software once you tell the software which file is supposed to be red or green. Each pixel on the tiff file can have a grayscale intensity of 1-128. This information is used by the software to produce the numerical values and the color intensity.
