Good news; you will be able to buy the 24-inch M1 iMac in the color of your choice starting next week.

The new M1 iMac is available in a wide range of colors including blue, silver, pink, green, purple yellow and orange. But, in order to get the last three colors, namely purple, yellow and orange, you have to place an order for it online. The other three are available to buy right from an Apple Store where the iMac is officially available.
