When blue partakes in some degree of the plus side, the effect is not disagreeable. Sea-green is rather a pleasing colour.
RED-BLUE.
We found yellow very soon tending to the intense state, and we observe the same progression in blue.
Blue deepens very mildly into red, and thus acquires a somewhat active character, although it is on the passive side. Its exciting power is, however, of a very different kind from that of the red-yellow. It may be said to disturb rather than enliven.
As augmentation itself is not to be arrested, so we feel an inclination to follow the progress of the colour, not, however, as in the case of the red-yellow, to see it still increase in the active sense, but to find a point to rest in.
