When individual color values from a HSBType as a PercentType are retrieved, it will be necessary to multiply that PercentType by 255 to obtain a standard 8-bit per color channel RGB.
Correspondingly, the for 16 or 32 bit representation, the percent type needs to be multiplied the percent type by 16^2 or 32^2, respectively.
When individual color values from a HSBType as a PercentType are retrieved, it will be necessary to divide the PercentType by 100 and multiply by 255 to obtain a standard 8-bit per color channel RGB.
Correspondingly, for the 16 or 32 bit representation, the PercentType needs to divided by 100 and multiplied by 65535 (2 ^ 16 - 1) or 4294967295 (2 ^ 32 - 1), respectively.
```java
//Example for conversion to 8-bit representation
// In rule body
val red = (MyColorItem.state as HSBType).red * 255
val green = (MyColorItem.state as HSBType).green * 255
val blue = (MyColorItem.state as HSBType).blue * 255
val red = (MyColorItem.state as HSBType).red / 100 * 255
val green = (MyColorItem.state as HSBType).green / 100 * 255
val blue = (MyColorItem.state as HSBType).blue / 100 * 255
