Color.Equals Method (Color, Color)
Tests whether two Color structures are identical.
Assembly: PresentationCore (in PresentationCore.dll)
Return ValueType: System.Boolean
true if color1 and color2 are exactly identical; otherwise, false.
Floating-point values can acquire a small degree of error when they are operated upon. The Equals method, the Equality operator, and the Inequality operator do not compensate for this and thus may not return the expected Boolean result.
The AreClose method uses a fuzzy equality algorithm that compensates for this floating-point arithmetic error by returning true for a comparison of two Color structures that are practically identical, but whose values may differ by a minuscule amount.
