# COLOR

Return a numeric value calculated by a combination of three colors (red, green and blue) and the alpha channel, in the RGBA color system. The result depends on the color system used by your computer.

### 语法

COLOR(红色; 绿色; 蓝色; 透明度)

Red, Green and Blue – required arguments. The value for the red, green and blue components of the color. The values must be between 0 and 255. Zero means no color component and 255 means full color component.

Alpha – optional argument. The value for the alpha channel or alpha composite. Alpha is a integer value between 0 and 255. The value of zero for alpha means the color is fully transparent, whereas a value of 255 in the alpha channel gives a fully opaque color.

### 示例

「COLOR(255;255;255;1)」返回 33554431

「COLOR(0;0;255;0)」返回 255

「COLOR(0;0;255;255)」返回 4278190335

「COLOR(0;0;400;0)」返回 Err:502 (无效参数) 因为蓝色值大于 255。
