The artist is a representative of op-art (short for “optical art”). His artistic principles are close to those of B.Riley, V.Vasarely, J.Albers Oleh Murashka is interested in the effects of pure colors combinations. His works are multicolor compositions, each color having several shades. The primary intention of the artist is to affect the sensitivity of the human eye; after staring at his works for some time, you can see the colors flickering and pulsating bringing to mind chromatic scale in music.

The colors, as well as sounds and smells, possess the property of improving our mood. Some of them are soft and calming; the others are stimulating and inspiring. The light influences the color property, so color shades have different effects depending on the time of the day. Light tones normally soft in delicate morning and evening daylight may lack expression in bright midday sun. On the other hand the colors that look not so bright in the midday (like blue or light blue) maybe even irritating in the morning and in the evening. The shades of red, orange and purple normally turn bright in the sun though in the evening they usually look soft.

Like tunes, flickering colors have an effect on our mood. They excite and attract us; we can experience them again and again without being overwhelmed. In the morning and in the evening they calm us down while in the afternoon they make us active and happy.

The beauty of the painting is delivered after you look narrowly at it for some time. It is a gradual and slow process but the discoveries in the end are thrilling.
