Write a program to draw a rainbow in the GraphicsWindow.

Hello Small Basic fans,

here is my rainbow FZSV873.000.

Description:

• This program draws six overlapping ellipses in different pastel colors to simulate a rainbow.
  
• The ellipses are centered horizontally and stacked vertically with increasing size.
  
• The last color blends into the background, creating a smooth fade-out effect.
  

Best regards

Nice effect, isn't red on the outer and violet on the inner edge.

Hello LitDev,
You're right — the colors of a rainbow are different. Here's an example with the correct color selection and order.

FZSV873.000-0

I had the color choices created by Copilot.

See you soon,

Hello everyone,

In version FZSV873.000-0, I find the colors too bright. I'm providing version FZSV873.000-1 instead. This version uses shapes with increased transparency.

See you soon,

Hello friends of the rainbow,

here is my new version FZSV873.000-2. In this version, commands from the LitDev extension are used.
At the beginning of the program, there are three variables that are assigned values. These can be used to change the appearance of the rainbow.

Have fun experimenting!
