I know that there’s been a few colour balances here and there but there’s a lot of evidence to suggest Steel wasn’t meant to be one of them.
Right now Steel has become some kind of lightish-grey. It’s VERY similar to every other colour on the black-white spectrum with the exception of Pepper. The Spartan renders on Waypoint also reflect this.
However, the smaller selection “slates” for Steel still show the older colour. As a result there is a disparity between the game’s UI and the actual colour that shows up.
In addition to this the correct Steel colour is available for Emblem colouring as well. Even the Sandboxr 3D Printing service still recognizes Steel as being the colour it was before the update.
Perhaps the most compelling pieces of evidence for this being a glitch, though, is the fact that Steel was shown correctly in the previews for Hammer Storm on builds that included the updated colours (as seen here - https://pbs.twimg.com/media/CbjGAR6UkAIcaFB.jpg:large). What happened between then and now?
