This tab allows you to control how the internally computed noise is turned into color for output.
此选项卡允许您控制如何将内部计算的噪声转换为输出颜色。
Color 1
颜色1
This is the color that is output where the computed noise is not present.
这是在没有计算噪声的情况下输出的颜色。
Color 2
色彩2
This is the color that is output where the computed noise is present. Where noise is partially present, the output will be a blend between Color 1 and Color 2.
这是输出计算噪声的颜色。在噪声部分存在的地方，输出将是颜色1和颜色2之间的混合。
Invert
This swaps Color 1 and Color 2 internally, essentially inverting the noise effect.
这在内部交换颜色1和颜色2，本质上反转噪音效果。

Min

This is the minimum allowed value of the internally computed noise.
这是内部计算噪声的最小允许值。
Max

This is the maximum allowed value of the internally computed noise.

Bias
偏见
This value is a contrast control that allows you to bias the output towards Color 2 when the bias is over 0.5 and towards Color 1 when under 0.5.
这个值是一个对比度控制，让你偏向输出的颜色2时，偏向0.5以上，偏向颜色1时，低于0.5。

The options below apply to 'Fractal' and 'Turbulence' Noise Types only.
下面的选项仅适用于“分形”和“湍流”噪音类型。
Complexity
复杂性
This option describes how many iterations or 'octaves' will be used to generate the noise, with higher iterations resulting in more complex, detailed noise and slightly slower shading.
这个选项描述了多少次迭代或“八度”将被用来产生噪声，更高的迭代产生更复杂、更详细的噪声和稍慢的阴影。

Distortion
失真
Controls the amount of distortion applied to the coordinates that define the noise seeds, to create plasma-style effects.
控制应用于定义噪声种子的坐标的失真量，以创建等离子体样式的效果。
Distortion is used in conjunction with Distortion Scale, Distortion Scale must be set to a value other than 0 in order for it to have any effect.
失真是与失真尺度结合使用的，失真尺度必须设置为0以外的值，才能产生任何效果。

- Constant - the current frame time is used to bias the noise computation 常数-当前帧时间是用来偏置噪声计算
- User - a user-defined time is used to bias the noise computation 用户-一个用户定义的时间被用来偏置噪声计算
