ZX Spectrum Graphic Modes - Multitech Monochrome

Multitech Monochrome

By reducing the colour settings of the TV or monitor, it is possible to take advantage of the differences in intensity over the Spectrum's colour range to generate a 15-shade grayscale image at 256x192 resolution.

This technique is most commonly associated with the MB-02's Multitech capabilities, although it would work equally well with any other hicolour method as described above.
