Silver. ±10%. None. ±20%. The first letter of the color code is matched by order of increasing magnitude. The electronic color codes, in order, are: 0 = B lack. 1 = B rown. 2 = R ed.
A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.
The color combinations are applied to the insulation that covers each conductor. Typically, one color is a prominent background color of the insulation, and the other is a tracer, consisting of stripes, rings, or dots, applied over the background. The background color always matches the tracer color of its paired conductor, and vice versa.

A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board. The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15. The number is sometimes followed by a letter, indicating that components are grouped or matched with ...
A new tool by researchers at the School of Science at IUPUI and Erasmus MC University Medical Center Rotterdam in the Netherlands can predict your hair, skin, and eye color from your DNA data.

Iron in biology. Iron in hemoglobin is the source of the red coloration of vertebrate blood. Hemoglobin diagram. Iron is an important biological element. [ 1][ 2][ 3] It is used in both the ubiquitous iron-sulfur proteins [ 1] and in vertebrates it is used in hemoglobin which is essential for blood and oxygen transport. [ 4]
