Haymarket - Mustard Yellow Paint Inspired by Haymarket's history of farmers selling their crops to Londoners. A dusty, mustard-yellow paint that is dark but vivid. The colour offers a different feel, and suits a contrast with dark shades just as well as it does with whites. Try Haymarket paired with a strong, dark blue such as Mayfair Dark (No 218) , or a deep red, such as Huguenot (No 49) to give a smart, yet warm and inviting feel to your living room or kitchen. Use Yellow Primer and Undercoat. Get inspired for your painting project and check out the whole range of paint colours on offer.
