Great Castle Sir Wolf!!!
The Klickies I think actually fit the heraldry ok.
In Medieval times they probably would not have been to exact in color.
So just having one color (red) and the device
Would probably have been period.
After all most people (peasants who formed the bulk of many medieval armies) were not rich enough
To go out and but the colors of their Lord.
They would probably only have had one tabard with their lords main color and device.
