Summary

Returns all objects whose Color property complies with the Query.

Syntax

Color : Numeric_String
Color : Number

The Color keyword can always be used in conjunction with a Numeric_String. It can alternatively be used in conjunction with a Number, but only when all Part objects (which do not have a Color property) have been totally excluded by one or more preceding entries within the Query expression. Either use entries in the expression such as Color <> '', Color > '', ObjectKind <> 'Part', or Not IsPart. Alternatively, use entries specifically targeting non-part objects, such as IsArc, etc.

The color corresponding to a particular number can be deduced from the following relationship:

65536 * Blue + 256 * Green + Red

where the Blue, Green, and Red components each have a value between 0 and 255 (inclusive).

When the Color keyword can be used in conjunction with a Number, it is possible to individually evaluate the values of each of the Color property's Blue, Green, and Red components, by using the following constructs:

  • Blue = Color Div 65536
  • Green = Color Div 256 Mod 256
  • Red = Color Mod 256

Example Usage

Color = '0'
Color <> '' && Color = 0

Returns all objects whose Color property is 0 (which corresponds to values of Blue = 0, Green = 0, and Red = 0).

Color = '16711680'
Color > '' && Color = 16711680

Returns all objects whose Color property is 16711680 (which corresponds to values of Blue = 255, Green = 0, and Red = 0).

Color <> '16777215'
Returns all objects except those whose Color property is 16777215 (which corresponds to values of Blue = 255, Green = 255, and Red = 255).

ObjectKind <> 'Part' && Color <> 16777215
Returns all objects – except parts – whose Color property is 16777215.

Not IsPart && Color Div 65536 >= 96 && Color Div 256 Mod 256 Between 64 And 192 && Color Mod 256 <= 128
Returns all objects – except parts – whose Color property is such that the Blue component has a value which is greater than or equal to 96, the Green component has a value which is greater than or equal to 64 and less than or equal to 192, and the Red component has a value which is less than or equal to 128.

IsArc Or IsBezier && Color Mod 256 Between 64 And 192
Returns all arc and Bezier objects whose Color property's Red component has a value which is greater than or equal to 64 and less than or equal to 192.
