Claim:
1. A method for operating a head-mounted computing device, comprising: capturing an image of a three-dimensional environment external to the head-mounted computing device, the captured image including at least a portion of a field of view of a user through an at least partially see-through display of the head-mounted computing device; identifying a first surface within the captured image that is eligible for color fill operation, based on similarities in color parameters of contiguous pixels in the captured image; receiving a color fill request via user input at the head-mounted computing device, the request being for a predetermined color; and performing a color fill operation on the identified first surface in response to receiving the color fill request by (a) generating a holographic overlay including a virtual object having the predetermined color and a shape with a boundary that conforms to the shape of the first identified surface, (b) displaying, through an image production system, the holographic overlay in a world-locked manner so as to overlay the first identified surface as viewed through the see-through holographic display of the head-mounted display device so that the virtual object remains in a fixed position relative to the identified first surface even when the perspective of the head mounted computing device changes.
