Yellow can be used without difficulty in the dining room, although red is slightly better suited there. If you want the colour to really stand out, go for yellow in the kitchen and/or bathroom. Yellow is great in such practical living rooms.
In the kitchen, one unconsciously associates yellow with food (just think of bananas, lemons, French fries, egg yolks, etc.). In the bathroom the colour also evokes freshness and summertime. Moreover, yellow is ideal for making smaller rooms seem bigger than they are.
Of course, you have to be careful not to overdo it, and definitely don´t paint the entire room yellow. According to some studies, such brightly-coloured rooms lead more quickly to feelings of frustration or anger. For a baby’s room, too, it´s better not to use yellow.
