LDcad Colors. Where is...?

[Philippe Hurbain]

The bluish greys should be 71 and 72. The color chart is here:

That said, LDraw color numbers don’t necessarily match Bricklink color numbers. Both systems were developed independently so there is mismatch.

Also note that there are too many colors in "solid plastic" and "transparent" families to fit in a single wheel. There are two little triangles next to the wheel that allows to change color page (bluish greys are in the second page of solid plastic).
Alternatively, you can mouse over the current color name and key in color number (eg. 71) + enter key to change current color.
