In my field of activity we use the term "organoleptic characteristics" to describe a substance's colour, smell, taste and touch.
I want to take this forward and make an organoleptic examination of happiness. Here is my research:
On the outside it appeared leafy green, with golden sunlight dots. On the inside i observed contrasting colours, vibrant and warm.
It smelled like roses and elderflowers. It tasted like homemade goodies and felt like a cooling breeze.
That' s how pure happiness looks like!
