Color is a tough challenge. So it’s best to pick a basic color and a transitional color that can be changed to another as the child gets older. This will give you the required flexibility to create new color combinations for the future. Greens and pale yellows for example is such a flexible combination. If you prefer a more traditional color scheme then a pale pink combined with cream at first can easily transit into a pink with red/navy or lavender. Similarly, a baby blue combined with white can transit into a blue combined with khaki and brown. In any case, don’t forget to paint the room with eco-friendly, zero VOC, non-toxic, odorless paint. There some quality brands that certify that they are asthma and allergy friendly.
