Found within the root bulb ? Triggered by a chemical catalyst Two types of pigment are formed ? Pheomelanin ? Eumelanin Both combine to create natural shades ??Natural tones are achromatic 色素种类 黑素细胞产生色素颗粒 ·产生在发根中 ·由化学催化剂促成 形成的两种天然色素 ·真黑素 ·外激素 两者混合生成天然色调 ·天然发色为鲜艳色 Principles of Colour颜色原理 Subtractive Primary Colours Red Magenta ??Red and blue are reflected, green absorbed Yellow ??Red and green are reflected, blue absorbed Blue Cyan ? Green and blue are reflected, red absorbed 减去基础色 红色 洋红色 ??红色和兰色被反射，绿色被吸收 黄色 ??红色和绿色被反射，兰色被吸收 兰色 青色 ? 绿色和兰色被反射，红色被吸收 Natural Hair天然发质 Depth Tone Colour depth is determined by quantity ? Greater pigment concentration = darker shade ? Eumelanin has more influence on depth ? Depth is represented by a scale (1 to 10) Colour tone is determined by type ? Combinations of eumelanin pheomelanin Tone is more evident as hair lightens ??Pheomelanin has more influence on tone 颜色深浅度和色调 颜色深浅度取决头发内色素数量 ·越多的色素汇集=越深的发色 ·真黑素对发色深浅度的影响更大 ·颜色深浅度表现方式分为1—10度 色调取决于色素类型 ·是外激素和真黑素的结合 ·发色越浅色调越明显 ·外激素对色调的影响更大 Natural Hair天然发质 Primary Undertones As hair is lightened, tones become evident Primary undertone will influence final shade Corrective colouring may be required 天然发色 发色越浅，色调越明显 天然底色会直接影响最终的染色效果 所以染色时有可能需要进行颜色修正才可达到理想 效果 Natural Hair天然发质 Behaviour of Pigments Eumelanin ? Is larger than pheomelanin ? Is broken down more easily ? Is
