If you are interested in improving your painting skills and learning more about achieving different techniques and the use of layered colour, then a great blog to follow is Colorways by Leslie Stocker.
Leslie's blog is full of inspiring pieces of furniture and the corresponding Annie Sloan Chalk Paint colours to achieve the look. I love the French Linen/Country Grey/Paloma/Old White mix above. It's very authentic of an aged patina. Unfortunately Australia's Country grey looks nothing like the above - ours is much more mustard beige. Actually the Australian version of Country grey is a big disappointment for me. I adore the colour that it in in the swatch above and in Annie Sloan's books but there's obviously a manufacturing colour drift in the paint we get in Australia and it's such a shame.
Leslie also has a fabulous colour swatch book that she has painted different colours and tints. She has then scanned the different tints on her blog. It's a great resource if you want to check some colours accurately.
BTW another tint mixer resources is the Paint Online Mixer from The Purple Painted Lady.
But I warn you, make yourself a cup of tea or coffee and settle in before clicking over to Leslie's blog - you will be there a while.
