Blue auras are very relationship-focused, with an emphasis on communication and holding space. Merrick notes that people who like blue in their home may have chaotic households and intuitively feel called to the serene, calming energy blue offers. Shades like indigo, cerulean, and even light blue will all work, and luckily, lots of shades tend to look good together. You can include blue anywhere, from your bookshelves, with little objects, vases, and the like, to pillows, blankets, rugs, and so on.
