RGB Lights

[XLjedi]

So, I have a composite MC with an on/off toggle and slider properties that let me set the R1,R2, G1... variables between 0-255 and that all works fine for a basic 2-color RGB light toggle.

However, I notice there are no On/Off connectors on the lights themselves?

Is it intended that the RGB color (0, 0, 0) is equivalent to Off?

...or do these things continue to draw power with a (0, 0, 0) color?

If so, I will probably just add an On/Off output to the MC that multiplies all the values by zero.

RGB lights require an input between 0-1 for each channel.
Putting out 0 on all channels emits no light.

Odd... it seems to take 0-255 just fine on my MC? I'm leaving it that way, it make far more sense.

I realize it emits no light... Does it draw power?
I'll just test it myself.

I confirmed the color [0,0,0] draws no power, so effectively it is the Off condition for the light.

...and I also stand corrected!

RGB is a 0-1 value for each channel. I didn't notice because I was just maxing out the sliders for Red, Green, Blue, etc. in my testing.

So, I just added the MC logic to scale my 0-255 input sliders to a 0-1 output and it all works fine now. Appreciate the heads-up there!

Putting in any value above 1 won't make a difference, since the light will produce the respective RGB value of 255 when receiving an input >=1.

The wiki and ingame tooltip tell you it needs a value between 0-1.
With all inputs at 0 it doesn't consume any electricity.

Won't see this if you only put in basic colors like 255 0 0 or similar.

Edit: Glad you got it figured, heh.

If anyone is interested in the RGB controller logic, I posted it here:

I love Stormworks for it is forcing you to create and compose solutions even for basic blocks and mechanics. It may be difficult for some players, but doesn't it motivate to learn new things?

Should note here that 255³ is only ca. 16.5M different colors, which is a very small spectrum compared to having in excess of a thousand values between 0 and 1 as decimal points. That's why vast majority of RGB, CMYK and HSV applications use floating decimals between 0 and 1 instead of byte numbers.

You're joking right?

I think I'm good limiting my light color options to just the 16.5 million. I also like to match the light colors exactly to the non-RGB lights which the devs seemed content using 0-255.

Indeed, there aren't too many sandboxes that are as nice.

16.5M colors is less than half of the visible color spectrum, here's a handy chart:

sRGB refers to 16.5M colors.

For comparison, here's an image in sRGB

And the same image in ProPhoto color range

Can you tell the difference?

I could honestly care less... we're talking about colors for blinky lights. I might need about 5 for my boat and I want to assign them consistently with 0-255 values from the in-game color selector.

As it relates to this thread (probably the whole game too) this is just pointless minutiae.

I think you're missing the point here. I'm trying to enlighten why they aren't 0-255 values :)

OK, great... the devs don't seem to care about it as an option for their standard color selector.

Repectfully, however. I do appreciate your input, thank you.

Someone at some point might find that bit of info helpful for their rainbow light dance machine engine.
