Yes, I said that. Just a wild thought, but some techniques used to accentuate areas in a painting could be considered like adjectives in writing. For instance, using a very dark hued palate for a painting to depict a somber, sad, or evil image is similar to using adjectives like black, stark, or malignant. On the opposite end, a bright-colored palate for a happier subject can resonate as lively, sunny, or cheery.
Using a painters knife to cut in thick, defined texture to rocky areas is a visual means (one I have not mastered) of showing rough, angular, and solid stone. Airbrush painting is a popular method of achieving soft, smooth effects in paintings such as silky, glassy, and gentle are for writing. Basically, artistic techniques are visual means of enhancing the meaning of a subject much similar to using adjectives to enhance the meaning of literature.
