Rainbow Astronaut

Appearance

The Rainbow Astronaut looks like a Red Astronaut at first. What makes it unique is its color-changing effect. The Blook rotates through a gradient of colors, it rotatest up to 5 different colour, which gives it a rainbow appearance.

Trivia

• The Rainbow Astronaut change the light wave length frequently.

let’s do some Science regarding the change of colour of this blook.

Visible light has wavelengths roughly in this range:

• Purple: 380–450 nm (nm means nanometer it’s wavelength of the light)
• Blue: 450–495 nm
• Green: 495–570 nm
• Yellow: 570–590 nm
• Pink: It doesn’t have a single wavelength it’s usually a mix of red (620–750 nm) and some blue light, so it’s more of a perceived color than a single wavelength.

Let’s approximate pink as ~650 nm for calculation.

If an Rainbow Astronaut rotates through these colors—Pink → Blue → Green → Purple → Yellow → Pink the approximate wavelength change is:

• Max wavelength (Pink) ≈ 650 nm
• Min wavelength (Purple) ≈ 380 nm

So the continuous wavelength change is roughly:

650 nm − 380 nm = 270 nm

Which means while going from one colour to other Rainbow Astronaut changes it’s light wave length to around 270 nm.

• There are four Blooks with “Rainbow” in the name: Rainbow Astronaut, Rainbow Narwhal, Rainbow Jellyfish, and Rainbow Panda.
• Out of these four, only the Rainbow Astronaut is a Mystical Blook. The others are Chromas.
• Both the Rainbow Astronaut and Rainbow Panda are obtainable Blooks. The others are unreleased.
• This is the only Blook that changes color every second as part of its animation.
• It is featured in cafe mode.
