Using other signals that are parallel to the color coding, such as patterns, shapes, size or order. This not only helps color blind people, but also aids understanding by normally sighted people by providing them with multiple reinforcing cues. Using brightness contrast (different shades) in addition to color contrast (different hues)
To achieve good contrast, conventional wisdom suggests converting a (digital) design to grayscale to ensure there is sufficient brightness contrast between colors. However, this does not account for the different perceptions of brightness to different varieties of colorblindness, especially Protans, Tritans and Monochromats. Viewing the design through a CVD Simulator to ensure the information carried by color is still sufficiently conveyed. At a minimum, the design should be visible for Deutans, the most common kind of colorblindness. Maximizing the area of colors (e.g. increase size, thickness or boldness of colored element) makes the color easier to identify. Color contrast improves as the angle the color subtends on the retina increases. This applies to all types of color vision. Maximizing brightness (value) and saturation (chroma) of the colors to maximize color contrast. Converting connotative tasks to comparative tasks by including a legend, even when the meaning is considered obvious (e.g. red means danger). Avoiding denotative color tasks (color naming) when possible. Some denotative tasks can be converted to comparative tasks by depicting the actual color whenever the color name is mentioned; for example, colored typography in "purple", or "purple (█)". For denotative tasks (color naming), using the most common shades of colors.
An ameboma, also known as an amebic granuloma, is a rare complication of Entamoeba histolytica infection, where in response to the infecting amoeba there is formation of annular colonic granulation, which results in a large local lesion of the bowel. Presentation
The ameboma may manifest as a right lower quadrant abdominal mass, which may be mistaken for carcinoma, tuberculosis, Crohns disease, actinomycosis, or lymphoma. Diagnosis
Biopsy is necessary for definitive diagnosis. == References ==
