Method of ensuring adequate contrast of graphical user interface elements

A method of ensuring adequate color contrast between graphical user interface elements, comprising the steps of:

• receiving a first pair of graphical user interface elements;
• receiving a first color of a first graphical user interface element of the pair of graphical user interface elements;
• receiving a second color of a second graphical user interface element of the pair of graphical user interface elements;
• setting a minimum contrast between the first color and the second color;
• determining whether a contrast between the first color and the second color is equal to or greater than the minimum contrast;
• if the contrast is not equal to or greater than the minimum contrast, designating the first color as locked, and designating the second color as moveable;
• and
• if the moveable color is closer to the color black than the locked color, moving the moveable color closer to the color black until the contrast between the first color and the second color is equal to or greater than the minimum contrast.

A computer readable medium having stored thereon computer-executable instructions which when executed by a computer, perform the steps of:

• receiving a first pair of graphical user interface elements;
• receiving a first color of a first graphical user interface element of the pair of graphical user interface elements;
• receiving a second color of a second graphical user interface element of the pair of graphical user interface elements;
• determining whether a contrast between the first color and the second color is equal to or greater than a minimum contrast between the first color and the second color;
• if the contrast is not equal to or greater than the minimum contrast, designating the first color as locked, and designating the second color as moveable;
• and
• if the moveable color is closer to the color black than the locked color, moving the moveable color closer to the color black until the contrast between the first color and the second color is equal to or greater than the minimum contrast.

A system of ensuring adequate color contrast between graphical user interface elements comprising a computer program module operative:

• to receive a first pair of graphical user interface elements;
• to receive a first color of a first graphical user interface element of the pair of graphical user interface elements;
• to receive a second color of a second graphical user interface element of the pair of graphical user interface elements;
• to set a minimum contrast between the first color and the second color;
• to determine whether a contrast between the first color and the second color is equal to or greater than the minimum contrast;
• if the contrast is not equal to or greater than the minimum contrast, to designate the first color as locked, and to designate the second color as moveable;
• and
• if the moveable color is closer to the color black than the locked color, to move the moveable color closer to the color black until the contrast between the first color and the second color is equal to or greater than the minimum contrast.

A method of ensuring adequate contrast between two colors, comprising the steps of:

• receiving a first color and a second color;
• setting a minimum contrast between the first color and the second color;
• determining whether a contrast between the first color and the second color is equal to or greater than the minimum contrast;
• if the contrast is not equal to or greater than the minimum contrast, designating the first color as locked, and designating the second color as moveable;
• and
• if the moveable color is closer to white than the locked color, moving the moveable color closer to white until the contrast between the first color and the second color is equal to or greater than the minimum contrast.

A method of ensuring adequate contrast between pairs of colors, comprising the steps of:

• receiving a first pair of colors;
• receiving a first color and a second color of the first pair of colors;
• determining whether a contrast between the first color and the second color is equal to or greater than a minimum contrast;
• if the contrast is not equal to or greater than the minimum contrast, designating the first color as locked, and designating the second color as moveable;
• if the moveable color is closer to the color black than the locked color, moving the moveable color closer to the color black until the contrast between the first color and the second color is equal to or greater than the minimum contrast;
• and
• if the moveable color is closer to the color white than the locked color, moving the moveable color closer to white until the contrast between the first color and the second color is equal to or greater than the minimum contrast.
