Signs are now a lighter color than their plank counterparts

I noticed that signs are now significantly lighter than their plank counterparts. I can only assume it’s a bug because it suddenly appeared within a recent update. I use signs with other wood blocks that match it and this glitch now makes it impossible to match up the blocks I have been using and it’s really aggravating visually. In the photo I show spruce signs being used in conjunction with spruce planks and oak logs, which usually match pretty closely in color.
