In art, value (or tone) refers to how light or dark a colour is. If you're learning to paint or draw, doing value studies is one of the best ways to improve. These small, loose sketches in greyscale help you understand where shadows fall and highlights appear—essential for capturing depth and form. Value Study is a simple, focused tool designed to help you see values more clearly in your reference images. Instead of just converting a photo to black and white, this app lets you break down tones step by step. Start with just black and white to map out the biggest shapes, then gradually add more values to refine your understanding. You can also highlight all areas of an image that share the same value, making it easier to see subtle shifts in tone. This is especially useful in complex references, like portraits, where different parts of the image might have the same level of shadow but look completely different in colour. Value Study isn’t here to replace traditional studies—it’s here to enhance them. Whether you're sketching, painting, or working digitally, this tool makes it easier to focus on the fundamentals of light, shadow, and form. Try it for free with all features enabled on sample images from Unsplash before deciding to unlock the full app with a low-cost yearly or lifetime purchase.

ChromaMagic - the magical color tool for artists - now with LIVE camera views. Have you ever been painting and said 'but what *is* that color?' Me too! ChromaMagic exists for one reason only. My paintings looked wrong. I just couldn't get the colors in my paintings to look convincing. Try as I might there was always something off. Too bright, too light, too gray, not gray enough. Too blue, too brown, too pink. Why oh why could I not make things work? Well it turned out it wasn't in the paint. It wasn't in the mixing. Special brushes didn't do the trick. Making those daft color charts didn't help either. And it wasn't even in the way I put the paint on the paper. The problem was in my brain. The problem was that I had no chance of mixing the right color. I was missing an essential part of the painting process. Something that would take years if not decades to figure out. And the reason was that I wasn't *seeing* the right color. Now I don't mean there was something wrong with my eyesight. What I mean that I was 'seeing' color but I wasn't really seeing *COLOR*. I didn't have the words or the means to really understand what I was looking at. And if we don't really know what we're looking at how on earth can we translate it into paint? Even if we don't want to represent what we see how do we know what to change to enhance the effect? Flip a coin? Trust chance and experimentation? Repeat for years and years until we stumble on something that works....? No. So what changed? Everything changed. I learned to forget about primaries, secondaries and tertiaries. I learned to ditch the traditional artists wheel. I learned to stop talking about 'warm' and 'cool'. I learned to see color the way it is and not the way I expect it to be. I had to forget everything I had been told. I learned about hue, value, and chroma. Munsell. With ChromaMagic you can load up any photo or reference and see at a glance what any color is. And the colors are described in a way that is most natural for artists. What is the hue (red, yellow, green etc)? Yes! And what is the value (very important)? Yes! And what is the chroma (how gray or saturated it is)? Yes!!! Color makes so much more sense now. But there's more! As well as the Munsell color mode (which is fabulous by itself!) there are 4 extra modes to help you really see what is before us. - Want to organize your reference into the major value shapes? Value mode will do that and you can change the number of value steps with a click of the mouse. - Want to reduce your reference to just grayscale to really see those fine-grained values? Yes! - Want to see how saturated or gray your colors are (this is always surprising!). Yes! - Want to see how your colors are distributed around the color wheel? Yes And yet there's still more: - No more clicking around - ChromaMagic has a fantastic new interface with buttery smooth zoomable, pannable images. - No more need to be tethered to wifi. Take ChromaMagic anywhere - even up a mountain! - Too many colors in your reference? Average your colors over multiple pixels - 2500 of them if you want to. - Want to know which paints are available for a certain color? ChromaMagic now has links to hundreds of top quality oil paints. - Want to use ChromaMagic at home? On the bus? On a tablet? Now you can run it on your iphone, ipad or mac. All for one price! - No more silly loading buttons. Drag and drop your files in one swish on the desktop (Bliss!!) - Use ChromaMagic next to the easel for mixing. Now with mixing swatches and calibration values (no need for $1500 Munsell chips)
