You can certainly see an ideal black body as long as its temperature is high enough to emit visible light.
The most common example of an ideal black body is a hole on an oven. The hole absorbs all light and reflects no light (because it is a hole, not a real surface) and the light that comes out is the average temperature of the oven.
