It is constructed by superimposing white discs on the intersections of orthogonal gray bars on a black background. Dark dots seem to appear and disappear rapidly at random intersections, hence the label "scintillating". When a person keeps their eyes directly on a single intersection, the dark dot does not appear.
Blue circles replace the intersecting blue lines, especially when viewed from a distance. Neon color spreading (also referred to as neon-like color spreading) is an optical illusion in the category of transparency effects, characterized by fluid borders between the edges of a colored object and the background in the presence of black lines. The ...
A test image for the anti-McCollough effect. On first looking at this image, the vertical and horizontal lines should look black and white, colorless. After induction, the space between vertical lines should look green and the space between horizontal lines should look red.
Overtaking is prohibited either for all vehicles or for certain kinds of vehicles only (e.g. lorries, motorcycles). In the USA, this is usually phrased as "no passing zone" and indicated by a rectangular, black-on-white sign on the right side of the road that says "DO NOT PASS", and/or by a solid yellow line painted on the roadway marking the left limit of traffic (centerline), and sometimes ...
Line art or line drawing is any image that consists of distinct straight lines or curved lines placed against a background (usually plain). Two-dimensional or three-dimensional objects are often represented through shade (darkness) or hue . Line art can use lines of different colors, although line art is usually monochromatic.
Example of White's illusion. White's illusion is a brightness illusion in which certain stripes of a black-and-white grating are replaced by gray rectangles (see the figure). Both of the gray bars of A and B have the same color, luminance, and opacity. The brightness of the gray rectangles appears to be closer to the brightness of the top and ...
Other works mix long lines of red amidst the familiar black lines, creating a new sense of depth by the addition of a colored layer on top of the black one. His painting Composition No. 10, 1939–1942, characterized by primary colors, white ground and black grid lines clearly defined Mondrian's radical but classical approach to the rectangle.
In page layout, illustration and sculpture, white space is often referred to as negative space. It is the portion of a page left unmarked: margins , gutters , and space between columns, lines of type, graphics, figures, or objects drawn or depicted, and is not necessarily actually white if the background is of a different colour.
