Red has longest wavelengths we can perceive with our eyes.

Longer wavelengths are infrared waves, microwaves and radio waves.

We can’t see these longer waves, but can we sense them?

I often wonder if we can feel red somehow.


When it is mixed with other colors it demands our attention.

      1. So glad you enjoyed it! Colors fascinate me, and it always irks me that marketing and advertising are so good at manipulating us with it. Kids are more easily manipulated than most, and the rebel in me really wanted to clue them in. 🙂


  1. It can be a difficult colour to place in the garden and even more difficult to photograph! You did a great job. I love the bleeding heart vine. It can only be a houseplant for me sadly.
