外番干货，色彩的原理

　　Hands down, on the ranking of the most important art principles, you find colour theory on a solid second place, only beaten by the most important theory; values. From all of the different aspects of art studies, colour studies are probably the most studied of them all, and it's probably also the hardest one to master. Staying on top and handling the most important principles of art will give your advantages in the art scene for sure and shouldn't be overlooked.

　　学习怎么控制色彩，在不同色彩理论中吸取精华，让你的艺术作品变得更受欢迎!

　　我们按照艺术理论的重要性来排列，你会发现色彩理论排在第二位，仅次于最重要的：明度(这里指的是用素描关系绘制体积)。在艺术研究的不同方面里，色彩研究也许是最深奥的。而且也许是最难精通的。我们能肯定的说，掌握和处理最重要的艺术原理能够让你的艺术作品增添魅力，而且这也是不容忽视的。

　　The main characteristics of colour

　　The principle of colour might seem simple enough, but taking the four main characteristics of colour into consideration; hue, value, saturation, and temperature, there are really no limit of what you can do with this if you know a little about how it all works. There's a lot of theory and studies on colour principles, and you don't need to know them all to be able to create nice compositions of colour, but knowing a few of them is a good start for any artist.

　　色彩的主要特性

　　色彩原理看起来好像很简单，但是我们来考虑色彩的四个主要特性：色相，明度，饱和度(也就是纯度)和色温(色温简单说就是平常大家说的冷暖)，如果你对这些色彩特性是怎么工作的了解一点的话，那么它们对你该怎么去画是毫无限制的。色彩原理的理论学科有很多种，不是需要了解所有理论才能创作出好的色彩作品，但掌握些理论对任何一位艺术家来说都是个好的开始。

　　Simultaneous contrast

　　同步对比

　　All colours and even greyscale values are influenced by their surrounding colour, and can be used in several ways to create the expression you're aiming for. This is important to keep in mind when choosing your palette, and if you're planning on having a strongly saturated and dominant background colour, make sure to put the influence of this colour into account early in the process when blocking in your composition.

　　Surrounding colours also influence grey-scale surfaces. Look at the centre example and notice that the grey circles seem to absorb some of their surrounding colour. This can be used to create some very special and interesting effects in your compositions. The grey circles at the bottom all have the same greyscale value, but are influenced by their surrounding value and therefore appears to be different from each other.

　　所有色彩甚至包括灰色，都会受到周围颜色的影响，色彩的这种特性可以通过各种方式应用到你的作品当中。当你选择色板的时候考虑到这一特性是非常重要的。而且当你打算用饱和度很高和面积很大的背景颜色时，确定在色彩草图之前的阶段就把颜色相互影响的特性考虑进去。

　　环境颜色同样会影响到灰色，看例图的中间一栏你就会发现灰色的圆点好像吸收了周围的颜色。这可以在你的作品中创作出一些特别而且有趣的效果。最下面一栏的例图中，圆点的明度都是一样的，但他们周围的颜色对圆点产生了影响，使它们看起来有了不用的明度。

　　The power of complimentary colours

　　补色的力量

　　Now, let's take a look at that slightly intimidating device known as the colour wheel; what would an article about colour be without one, right? When working digitally, the importance of the three primary colours (the triangle in the centre) aren't that important as you mix colours differently on the computer, but you can still use this wheel to figure out your complimentary colours. If you look at the outer ring, the colours positioned perfectly opposite each other are complimentary to the other; red versus green, blue versus yellow, and so on. These colours have the strongest contrast, colour-wise and are a good choice to use in areas of interest to bring out attention to specific part of your painting. Mix the two complimentary colours, and you end up with a neutral colour.

　　现在我们来看下这个有点诡异的东东，大家都管它叫色环~色环对于色彩作品来说是多么的不可或缺啊，是吧?当我们进行数字绘画时，三原色(中间的三角形就是三原色了)的重要性比你自己在电脑上调出来的各种颜色差远了，(其实传统绘画不也这样嘛。。。都用原色画会崩溃的。。= = 老外废话多?)但这个色环会指导你补色的运用，外环上颜色的位置很好的显示了补色位置，红对应绿，蓝对应黄，等等。(色环上相对180度的颜色互为补色)这些颜色有着很强对比度和色性，用这些颜色来突出画面的视觉中心，增加画面趣味性是个不错的选择。把互为补色的颜色混合得到的是偏中性的颜色。

　　Simon Dominic is using complimentary colours on this painting to bring out the purple birds towards the green main element in the composition.

　　Colours have weight, and it's quite simple; the darker the colour, the more solid and heavy the painted object will appear. The brighter colour and values, the lighter and more delicate the painted object will seem. You should use colour weight to balance your composition, and for creating striking moods. Philip Straub is using colour weight to bring out the main element in focus and balancing the composition in this painting. This is a great way to empathize areas when you're working within a limited colour range and don't want to use complimentary contrast as an attention seeker.

　　颜色有重量感，非常简单，深色看起来更重，存在感比较强，亮色和明度高的颜色看起来更轻更精致，亮色画出来的东西比较虚无飘渺。画面需要色彩的量感来平衡，并以此取得吸引人的气氛。Philip Straub(上图作者名)用颜色的量感来突出主题元素使画面得到平衡。这是当你只能用有限的颜色和不想使用补色的时候，用颜色的量感突出视觉中心的很好方法。
