The T10 is the same appearance as wing side indicator bulb. number plate illumination bulb, sidelight bulb, etc but lower wattage. These seem to be used as the general instrument cluster illumination.  

T5, 1.4 watt should be easy to find. These are typically used to highlight a specific function, not for general illumination.

The colours are created by rubber skins that cover the body of the bulb. These can easily be removed from your blown bulbs are refitted to standard clear replacements.
