  One of the projects that I am working on involves an interactive display able to convey a message in 12 different languages, so the use of "universal icons" are a big thing to think about when laying out the design.
  
  For your circumstance, I would consider ...
  
  Blue for Wet
  Brown for Dry
  
  ... additionally you could migrate or fade between the two depending on how dry or how wet your sensor is reporting.

  For greenhouse temperature and humidity indicators blue > red > yellow for cold > warm > hot, and green > yellowish/green > brown for wet > damp > dry has gone over pretty well.

  I would use color theory as my guide. Wet would be blue and dry is red. This gives you a wide range of dampness colors that are easy to differentiate from each other. A single WS2812B can only make colors on this wheel. With the exception of white. If you use multiple WS2812B and combine colors then you could hit brown. Orange & yellow should be close. I think.

  I should have mentioned I will be using Red, Yellow and Blue for temp. Kwinn's idea sounds feasible. I will be using multiple LED's, just not sure how many yet. Thanks for the input.

  RGB or RYB, brown is not easy. If you succeed please post. I want to see brown light.

  I am trying to get the timer to generate a (The diagram"WS2812 www.ledlightmake.com/rgb-addressable-led-strip-c-80_87/led-ws2812b-addressable-digital-stripsmd5050-strips-60-pcsm-p-216.html Protocol") squarewave using the output with 8bit MCU by sensor signle

  Well I have to confess that the closest I could get to brown was more of a dark orange, and it took a bit of trial and error to get that.

  Brown<>Orange same thing if your brain think one is in the shadow.
  The orange tile is the same color as the top brown tile.

  Well the humidity indicator cards that come with some semiconductors suggest dry = cyan and wet = pink.
  (cobalt chloride)

  I don't think it really matters much what color scheme you pick for humidity. For temperature blue for cool, red for hot, and yellow for very hot is pretty much a defacto standard. AFAIK there is no such equivalent for humidity. Since relative humidity has a range of 0 - 100% using the resistor color code to represent steps of 10% would be as appropriate as any other scheme, particularly for the folks on this forum.
