Constructional building set comprising building elements for person with color vision deficiency, and such building elements

Abstract

A building element for a constructional building comprising a top face, a plurality of side walls extending downwardly from the top face, a plurality of coupling studs which are arranged on the top face, a plurality of cavities arranged in a two-dimensional periodical pattern between the side walls to receive the coupling studs in frictional engagement and at least one color indicator which is part of the building element and indicates the color of at least one surface area of the building element. The color indicator is a symbol or a model of a real object. The color indicator also represents the shade of the color of the building element. The color indicator is a three dimensional space positioned within the the external surface of the said building element or is a three dimensional protruding structure positioned on the external surface of the building element or is printed on the external surface of the building element. The color indicator which is in the form of protruding three dimensional structure can be released from the external surface of the building element. Same color indicators are positioned on more than one side walls of the said building element allowing the perception of the color when color indicator on other wall is not visible. The position of the color indicator or the dimensions of the color indicator may be used to represent color of the building element. Multiple color indicators may be combined together to represent a new color. The building element may have boundaries to indicate the color of a specific area on the surface of the building element.
