 | | Even when the colors are fairly similar, the eye enhances them, rendering close pairs like Algieba (Leo's Gamma star) still quite lovely, some observers seeing them as orange and yellow, others yellow and greenish. |
 | | To the eye, Algieba shines at mid-second magnitude, but even a modest telescope under good atmospheric conditions will allow you split the pair, one appearing at bright third magnitude, the other at bright fourth, separated by just under five seconds of arc. |
 | | The brighter, the more orange of the two, is a class K giant with a temperature of 4400 Kelvin, the fainter a somewhat warmer (4900 Kelvin) class G giant, making it the yellower one. |
