M-Business Client displays images in color on devices that have color displays. On grayscale or monochrome devices, M-Business Client converts the color images to grayscale. The original color scheme of an image plays an important role in the way M-Business Client renders it on grayscale and monochrome devices. The process we employ to convert color images to black and white ones works best on images that have a high-contrast ratio between colors and that have crisp edges in the details of the picture.
