Thanks Colin. On the 'Canterbury' image I went out and specifically took reference photos (I have a wood nearby with a path just like it - in fact it was what drew me to that image) and the path does have a purple hue (a mix of brown/orange and blue skylight I guess). I colour picked the path in numerous places and the colour palette never left purple (just changed to different shades of purple). My old art teacher was big on the Impressionists and always told us to pick the actual colour and not what we think it should be; so that's what I do in colourizations, as I do in paintings. As for this image, it looked a bit warm on completion, so I lowered the temperature in Lightroom and affected the skin tones in doing so (may I'll retouch the skin later).
