121024 Grey mixing, a photo by borromini bear on Flickr.

thanks for all the comments (more on flickr and fb!)- this was my first attempt(from last night before getting your comments) at mixing greys using all kinds of combination of burnt sienna and pthalo blue – adding my perm rose or lemon yellow and also trying with some indigo… none of these achieved the colour I use A lot (which is so easily mixed with BS and French ultramarine) I will experiment further but I DO need to be able to mix a good neutral grey quickly and consistently.
