But the specs mention that the TMC will image in the panchromatic spectral region of 0.5 to 0.85 m. That means it covers all spectral bands.

Spectral bands

Blue - 0.440.52 μm.
Green - 0.50.59 μm.
Red - 0.630.7 μm.
Near infrared - 0.760.85 μm.

Now what the heck is going on here? Colour or black/white? Can someone elucidate this? Confusion confounded!
If the TMC is in broad visible spectrum why it is not transmitting color pictures?
