Every colour is different. With the inherent quality of building up moods, the implications of the use of colours change drastically. In my opinion, combination of colours along with perfect background is way more effective than a monochrome view.
Personally, yellow is not something I find attractive often. That’s why my photo library lacks images portraying yellow as a dominant one. After scrolling up and down for a while, I found this picture of a roadside common flower at a rural railway station. I was minutely watching the ant which was really busy searching the nectar . In a chilling afternoon on the backdrop of setting Sun, while strolling alone in a distant, lonely railway station – I found this small tree as my dear companion until I boarded the train.
