For digital publishing, sure. In academic publishing, for print, or if the same file is used for both digital and print copies, colour pages are often clustered together to reduce the production cost. If you have 20 pages of mostly black and white text each with a small colour figure, you have to print 20 colour pages. If you cluster them together, you can print 18 black and white pages and 2 colour pages instead.

This practice will go away as all publishing moves to digital formats. But as long as there is a print version for purchase as well, it will be more cost-efficient to organize papers like this.
