变暗

加深

提示

This blending mode is called “Burn” in English.

它是 除去 的变种，在 Photoshop 等部分软件中也叫做“颜色加深”。

将下层颜色数值反相，然后用上层颜色数值从结果中除去，最后把得到的结果反相。这会得到一种受下层颜色影响的变暗效果，类似于传统摄影暗房的加深技术。

1_{[1_Darker Gray(0.4, 0.4, 0.4)] / Lighter Gray(0.5, 0.5, 0.5)} = (-0.2, -0.2, -0.2) → Black(0, 0, 0)

1_{[1_Light Blue(0.1608, 0.6274, 0.8274)] / Orange(1, 0.5961, 0.0706)} = (0.1608, 0.3749, -1.4448) → Green(0.1608, 0.3749, 0)

Easy Burn

提示

This blending mode is called “Easy Burn” in English.

Aims to solve issues with Color Burn blending mode by using a formula which falloff is similar to Dodge, but the falloff rate is softer. It is within the range of 0.0f and 1.0f unlike Color Burn mode.

Fog Darken (IFS Illusions)

提示

This blending mode is called “Fog Darken (IFS Illusions)” in English.

Darken the image in a way that there is a ‘fog’ in the end result. This is due to the unique property of fog darken in which midtones combined are lighter than non-midtones blend.

变暗

提示

This blending mode is called “Darken” in English.

比较上下两层的颜色数值的亮度，上层颜色只有在比下层颜色暗时才会显示。

Is Lighter Gray(0.5, 0.5, 0.5) darker than Darker Gray(0.4, 0.4, 0.4)? = (no, no, no) → Darker Gray(0.4, 0.4, 0.4)

左： 正常 ；右： 变暗 。

Is Orange(1, 0.5961, 0.0706) darker than Light Blue(0.1608, 0.6274, 0.8274)? = (no, yes, yes) → Green(0.1608, 0.5961, 0.0706)

较暗颜色

提示

This blending mode is called “Darker Color” in English.

左： 正常 ； 右 较暗颜色 。

Gamma 变暗

提示

This blending mode is called “Gamma Dark” in English.

从 1 中除去上层颜色数值，然后把结果作为下层颜色数值的乘方。

深灰 (0.4, 0.4, 0.4) ^ [1 / 中间灰 (0.5, 0.5, 0.5)] = 极深灰 (0.1600, 0.1600, 0.1600)

左： 正常 ； 右： Gamma 变暗 。

浅蓝 (0.1608, 0.6274, 0.8274) ^ [1 / 橙 (1, 0.5961, 0.0706)] = 绿 (0.1608, 0.4575, 0.0683)

线性加深

提示

This blending mode is called “Linear Burn” in English.

把上下两层的颜色数值相加后减去 1，效果和 减去反相值 类似。

[Darker Gray(0.4, 0.4, 0.4) + Lighter Gray(0.5, 0.5, 0.5)]_1 = (-0.1000, -0.1000, -0.1000) → Black(0, 0, 0)

左： 正常 ； 右： 线性加深 。

[Light Blue(0.1608, 0.6274, 0.8274) + Orange(1, 0.5961, 0.0706)]_1 = (0.1608, 0.2235, -0.1020) → Dark Green(0.1608, 0.2235, 0)

Shade (IFS Illusions)

提示

This blending mode is called “Shade (IFS Illusions)” in English.

Basically, the blending mode only ends in shades of shades. This means that it’s very useful for painting shading colors while still in the range of shades.
