The joint-sealing tape of flexible foam capable of recovering its shape after compression with two lateral surfaces ( 3, 4 ) is colored on at least one of the two lateral surfaces ( 3, 4 ) with a colorant in such a way that, in a partially expanded functional state of the sealing tape, i.e., in a state of partial recovery after compression, the coloring on the lateral surface ( 3, 4 ), when viewed from the side, appears to the human eye as a continuous colored surface.
