Consider adding a splash of paint to brighten your kitchen as a cheap, fuss free solution. White enhances the light, so an all white colour scheme is guaranteed to create the illusion that your kitchen is more spacious than it is. A great trick is to paint your ceiling the same shade as your walls as this gives the effect of the ceiling appearing higher than it actually is.
If an all white kitchen is not your style, then opt for a touch of colour on your cupboards, drawers or perhaps a small table. Stick to a clean, pastel palette so you’re injecting enough personality to your kitchen without diminishing the illusion of space.
Remember to opt for specialist kitchen paints that are specifically designed to cope with splashes, moisture from cooking and every other bumps you expect to get in the kitchen.
