As they grow, their feathers start to resemble those of adult blue tits, with the characteristic blue, yellow, and white markings. **

Construction plans are traditionally printed on blue paper because the blue background makes the white lines and text stand out more clearly, making it easier to read and interpret the intricate details of the design. The blue color also helps to reduce eye strain for those reviewing the plans for long periods of time. Additionally, the blueprints are often reproduced through a process called cyanotype, which uses ammonia and iron compounds to create the blue background. **
