COLOUR  THEMSELVES

(色彩本身)

       The seven colour contrasts originated from the colour theory of Johannes Itten. This approach is not based on physical and chemical properties of colours, but on their subjective effects.
       The primary colours yellow, redand blue produce the strongest  contrast. The colour contrast becomes weaker with secondary or tertiary colours or as the saturation decreases.

 LIGHT-DARK

（亮与安）

            The “non-colours” black and white produce the strongest contrast. Even with the “proper” colours, their effect is significant. A light colour next to a dark colour has a stronger effect than next to an equally light or lighter colour. The effect of hues can be intensified by greater differences in brightness.

COLD-WARM

（冷-暖）

In the colour wheel, the warmcolours with red and yellow components are located opposite to the cold blue hues. Green and magenta form the neutral transitions.The effect of a predominant colour can be increased when combined with an accent from the opposite colour.

The pairs of colours lying opposite in the colour wheel form the complementary contrast from a primary colour and the secondary (mixed) colour made of the other two primary colours. Yellow-violet displays the largest light-dark contrast, orange-blue the largest cold-warm contrast. Red-green have the same light intensity. The complementary contrast causes the brilliance of the colours to increase.



SIMULTANEOUS

（同时）

         The effect of the simultaneous contrast has its origin in how the eye processes perception. After staring at a colour for a long time and then looking at a neutral grey, the eye forms a simultaneous contrast colour. Red leads to a green tinged grey shade. Green causes a grey area with a red tinge to appear. Colours change their effect due to the influence of the surrounding colours.

COLOUR  CONTRST

Quality

     The quality contrast, or intensity contrast, describes the distinction between pure colours and murky colours. Mixing pure colours with grey shades makes the former murky and dull, and the quality of colour purity is lost. Pure colours have a dominating effect over murky colours.

Quantity

         The quantity contrast refers to the relationship of the size of one coloured area with the next. A large coloured area with a small area in a contrast colour increases the chromatic effect of the main colour.

这是一张光色图谱，通过科学测试，人在什么色温环境下，视觉是最为舒适的，眼睛不疲劳。以及不同颜色视觉环境空间给人心理上和精神上都是不一样的感受！紫色空间往往通过视觉神经会刺激到人肾上激素分泌，达到兴奋状态（为啥红灯区的颜色是紫红紫红的，以及一些KTV、情调酒店以及杜蕾斯广告和包装等，），这里就不多赘述了.........

       这是国外一些产品设计，一些科学分析方案！通过颜色的分析和理解，我们在实际项目设计过程，我们的产品颜色视觉定位很重要，人群和职业背景不一样，对色彩敏感度都不一样，（a: 老人、小孩、女孩、色盲................b:艺术设计、科技IT、餐饮、医生、工人...............）

老人由于有各种眼睛疾病（青光眼，黄斑病、、、）在这设计项目中如何考虑到视觉要素重要性。如何提高设计的水准，就取决与我们对人群对象研究是否深刻。

这就让我们明白再设计海报、工业产品、环境标示系统等等，色彩视觉要素系统的重要性，因为他会影响到整个人群对产品直观感受！

后续将还会分享颜色的视觉导向性，以及颜色科学应用技巧........
