Shedding light on the colour matching process
The PPS Colour Check Light introduced by 3M, achieves a virtually perfect match to the colour spectrum of natural daylight
Depending where the vehicle is located in the crowded workshop or where you are in the repair process; the quality of lighting, the time of day or current weather conditions; whether the sun is shining or not – then the refinisher’s task of achieving an accurate, first-time colour match is made more difficult.
Imagine not having to worry about ambient light conditions and not being concerned that when the car is picked up by its owner in bright sunlight, that your spray-job; that was done under fluorescent lights, is not criticised or even rejected. Not forgetting, of course, the huge costs involved with a re-work.
Well help is at hand, because 3M has developed a hand-held light that can be used to check the colour match in what is a near perfect copy of natural daylight.
The portable PPS Colour Check Light uses a patented bulb that gives a virtually perfect balance to the colour spectrum of natural daylight whilst electronic systems maintain and control the light balance, regardless of the level of battery charge. There are two intensity light settings – Standard for mid-range colours and metallics, and High Intensity for darker colours or for use in extremely poor lighting conditions.
Daylight is characterized by a full and even light spectrum, without spikes, across the visible colour range. Daylight with its even spectrum is the best light source for viewing colours. For an artificial light source to mimic daylight properly it must have a light spectrum very close to daylight; otherwise it will affect the accuracy of colour judgement.
|The Colour Check Light from 3M is also useful for identifying paint defects such as swirl marks, holograms and sanding marks.

Lights used in bodyshops can have an uneven spectrum and colours will therefore look different. The ability to spot minor imperfections and the need to examine colour from different angles and see complete coverage under fixed lighting is extremely difficult even for the most experienced sprayer.
The PPS Colour Check Light from 3M has a spectrum virtually identical to daylight and therefore colours look the same as in daylight. The Light can therefore reduce the chance of costly re-work caused by colour mismatch, poor coverage or metallic layout as well as pre and post-paint defects like swirl marks, holograms and burn-through.
The Light can also be a big help for estimators when they are assessing vehicle colour and where incorrect identification is an easy mistake to make. Xirallic paints for instance - that can look like regular paints in normal lighting - can now be easily identified and the risk of this potentially costly error removed.
