Not too much at first to judge the needed portion for going another step to more chroma. Take your Value 6 Neutral and mix the orange in. How to mix neutrals and store mixtures in bulk can be read here). In case to match this particular color mix a pile of yellow and red (for example Cadium Yellow and Cadmium Red) to a strong chromatic orange. In fact this color is 2.5YR 6/6 in the Munsell Notation System which means a yellow-orange hue of 2.5, a value of 6 with a chroma of 6. It’s lightness is about half dark and half light – so it’s about value 5 or so. The chroma is neither neutral/grey nor full strenght. So it must be a yellow-red or simply orange. This color definetly is neither blue nor green. It defines colors by Hue (red, yellow, blue, green, blue-green, yellow-red ect.), Value (the lightness of a color starting at 0 for a perfect black up to 10 for a perfect white – both can`t be represented by tube paints), and Chroma (purity of a color the lower the chroma the more it tends to a neutral grey). The Munsell color system is the most logical color system – forget about other color systems. ( Here I show you a low budget glass palette with which you can place color chips beneath to make matching colors much easier). Now to the practical part for mixing colors on your palette. This explanation makes clear that a true color model is not circular but rather linear – wavelengths decrease or increase and become invisible for the eye. But we also notice that both ends – violett and red – are very similar and can indeed go from one to another. Between these wavelengths we can see every color – starting with violet at the low wavelengths up to red at the high wavelengths with every color in between. The eye perceives waves which have wavelengths between 380 nanometers and 780 nanometers. The eye is the organ that is able to perceive these wavelengths. There are different types of color models and most of them are organized in a circle. Color is a visual sensation of electro magnetic waves. But this did not help me learning to see and mix color. With my background as a lab technician I knew about the wavelengths of light and how the eye perceives color. Color theory – a little physics for the artistįor me color theory was always a boring topic.
