Agreed 
 
I have no strong views either way regarding Munsell versus Norbury approach --- the key point is to benchmark the colour description to a "standard" chart for consistency --the simpler the better.  Chemical analysis will be the final arbiter of contamination. 
 
If you recall the original question that I responded to from Sophie was in regard to lack of consistency in colour description and perceived difficulties by practitioners.

Subject: RE: Soil colours 
 
I would disagree with using Munsell colour charts as the choice of the colours is somewhat subjective and not helpful to contamination assessment.  Deciding which of the 325 colours in the charts takes a lot of time for limited or no benefit.  The cost of these charts is relatively high for what I believe is a hindrance to people doing soil description.  Who knows what" Gley 8/5G" means and what difference is that to "Gley 6/10Y" or "5YR 5/8"?  I recommend just sticking to the colours in BS5930:2015 (plus cream and orange) as there are plenty to choose from.  If you want a colour chart use the colour chart on David Norbury's Website which are the Pantone colours used by professional printers, see 
   
http://drnorbury.co.uk/wp-content/uploads/2015/08/Colour-Chart.pdf 
 
Colours can be indicative of contamination but most of the time there is no link from colour to contaminants other than the relatively common hydrocarbon contamination or if you are in Widnes (and parts of Glasgow etc) the cream and yellowish brown colours can be Galligu.  Bright colours and unusual colours can be indicators of contamination so you can add another sentence after the main description to add additional information if you think it is helpful.  Unusual colours observed are usually not indicative of a specific contaminant as there is often a cocktail of different natural materials and anthropogenic materials present. 
 
Oh, "Gley 6/10Y" is known to me as "grey" and "5YR 5/8" is "orangish brown."

Use a Munsell colour chart to avoid ambiguity ??

Subject: Soil colours 
 
Dear all,  
 
Thank you to those who have recently taken part in my questionnaire - the results are very interesting! 
 
I've been working through some of the questions and many of you have said that describing colour is difficult during logging. As part of my research to standardise colours, I have been researching different colours that can be present within soils. If anyone has encountered interesting or unnatural colours within soils during a ground investigation due to contamination or other sources and knows what has caused the colour, I'd be very interested in including it in my project.  Any pictures you have will also be very helpful.  
 
 
Kind regards, 
 
Sophia
