lime green, turquoise, rasberry, red, duck egg blue, pale blue, blackcurrant - you already have a neutral scheme, you could go for pretty much anything - do you want a warm or a fresh look?
You could try to "unite" the contrasting colours of white and dark brown with something like caramel. And to that you could incorporate something peachy, but don't go heavy-handed.
Thank you for your prompt responses. Much appreciated. Didn't think that it would go with all the colours as mentioned above! Will need to look around and find something that I really like e.g. painting as mentioned above and use the colours within this to build around it.
Thank you for all your suggestions. Much appreciated. I am looking to add orange (terracotte) ,black and white together. Would this go with the colour foundation that I already have in place?
Would appreciate comments,advice and suggestions regarding this.
