This makes sense as you stated that it wasn't visible in the colour images. This means that there is no colour data to add for the cluster. Maybe it should be left as monochrome or fudge it by moving all the colours 1 colour to the red. ie use the BGR channels on GRI and don't use the B filter at all. Still use the I filter as the lum though.
