A dataset of all paint colours carried by Dulux Australia, collated by scraping the Single Page App's API.
While building a new house we had to pick out the default colour of our walls. We liked the warmth of Manorburn but wanted the lightness of Lexicon. When you browse the colours on the website, in the colour info, all colours are defined by a Red, Green and Blue tint/tone/shade strength, and a Light Reflectance Value (LRV) which indicates how bright the paint is. Using the RGB values you can quickly search for colours, and you can use the LRV filter the brightness. Mathematically choosing colours using the Dulux website is impossible, and delving into the details of each colour to see if it matches the criteria would have taken a long time.
In our instance, we knew the colour we liked was "warm" ie equal or similar amounts of red and green, and lower amounts of blue. Being a grey colour the variation between all 3 tints are minimal. Additionally we knew the colour we wanted was a light as Lexicon, so it had to have an LRV around 84.
The data can be input into a command-line JSON processor like jq, which allows you to slice, filter, map or transform the data with ease.
cat data/colours.json | jq '.colours | map(select((77 <= .lrv) and (.lrv <= 86) and (0 <= .red-.green) and (.red-.green <= 4) and (0 <= .red-.blue) and (.red-.blue <= 9))) | sort_by(.lrv) | map({name,url})'Which results in:
