Art Materials Made Much Easier... Alright, so one of the most important (and easiest) steps you can take to improve your artwork is this... Significantly reduce the number of materials you use. That means fewer colours, brushes, pencils and mediums per drawing or painting than you're probably using right now. Here's common myth #1 that many amateur artists believe (at least subconsciously): More colours will make my life easier because I won't have to figure out how to make the exact colour I need from what I've got. But what happens is that you end up obsessing over which colour is the very best match. You learn nothing about colour mixing or creating harmony. Plus, it becomes very difficult to just enjoy the process of making a nice piece of art because you're constantly second-guessing yourself. And common myth #2? Limited materials means I'll only get to try limited styles and limited subject matter. The thinking goes, that if all you have is a single set of 24 coloured pencils or half a dozen watercolours for example, you're sure to come across subjects that require colours that you simply don't have and can't mix. Not true. I have yet to find a subject where I've needed to buy additional colours over the very limited amount I use. I don't obsess over precise colour matches like some artists - as long as I get the lights and darks right, the image will work. Unless you're a professional artist who's adamant that your art should be indistinguishable from the reference photo, then you shouldn't obsess over precise colour matches either. Whether you paint in colour or draw in monochrome, less is more. Fewer pencils. Fewer paints. Fewer brushes. Fewer surfaces. It will save you money. It will save you frustration. And you'll get to grips with the important techniques (like value, composition, proportion and harmony etc.) more quickly. And yes, you'll still be able to experiment with a really broad range of styles of subjects. So there's now only one thing for you to figure out... What limited materials should you pick, for the mediums you're most interested in, that will give you the most flexibility? Actually, you don't have to figure that out...
