There’s a decorating guideline that dictates that things displayed in odd numbers, with “3” often being the go-to number, adds depth, looks more natural, and makes arrangements more visually appealing than even-numbered groupings.
Three isn’t considered a crowd when it comes to arranging furniture, displaying artwork on walls or positioning contents on a tabletop. In fact, even adding a third colour to a room can change a flat design into something that feels more welcoming. For example, you may follow the 60/30/10 equation when choosing room colours, where 60% is the main room colour, 30% is the secondary colour and 10% is the accent colour.
Lighting arrangements also benefit from the power of three. Most rooms need to be lit by one ambient light, along with task lighting and then accent lights, all of which work together to result in a balanced and practical combination.
