Tria and HSLThe Tria Colour Space is based on a universallyaccepted colour model - HSL.HSL stands for Hue, Saturation and Luminosity - thethree basic elements used for determining any colour.Hue : R (red)9 - 8 - 7 - 6 - 5 - 4 - 3R555R547R576R528R519T9These elements can be shown as a three dimensionaldiagram. The Hue scale goes around the outer edge,with Saturation on the horizontal axis and Luminosityon the vertical.HSL uses the same bases as human colour perception.It’s naturally intuitive - a way to actually navigate andmanipulate colour.9 Saturation 151Luminosity1 Saturation 91 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9Hue : C - (cyan)HSL is represented as numerical values - meaningaccurate colour specification that can be interpretedby a computer.Most graphic software applications use HSL, so bysharing this method, the Tria colour space worksalongside the digital design process.Adobe Colour PickerApple Colour PickerG956 (blue/green)Tria colours are easy to identify and control - each reference tellsyou the HSL levels for that colour.
