Looking for RGB human-readable definitions

Using Arduino Programming Questions
1

with FastLED one had the nice feature that returned colors like:

       Olive=0x808000,
        OliveDrab=0x6B8E23,
        Orange=0xFFA500,
        OrangeRed=0xFF4500,
        Orchid=0xDA70D6,
        PaleGoldenrod=0xEEE8AA,
        PaleGreen=0x98FB98,
        PaleTurquoise=0xAFEEEE,
        PaleVioletRed=0xDB7093,

I can't use FastLED no more, due to bad STM32 support - but it would be nice to find definitions that return colors in the typical three-byte format like (0,23,65)

I am sure somebody has a good set of definitions I could use..

But you can still use the color definitions from pixeltypes.h. Cut and Paste

I think it's the same thing except hexadecimal and without a comma...

So for example 0x6B8E23 is...
6B hex = 107 decimal
8E hex = 139 decimal
23 hex = 35 decimal
= (107,139,35)

I used the Windows calculator in "programmer mode" but of course you can also do the "conversion" in software... You can mask & bit-shift to get one byte at a time.

Once you have the RGB byte values/variables they are actually in binary and it doesn't matter if your program uses hex or decimal as the programming/input/output format.

@blh64
I know guess I can use it with slight formatting like:
#define OrangeRed (0xFF, 0x45, 0x00)
or do you have an even simpler method?

Unlikely anyone needs so many named colours, also this will eat the board memory

7

Those names are really arbitrary without gamma correction and a colour space. I've done stuff like that, but with really obvious colours.

8

Feel free to tell the W3C. They are the ones who chose to define 140 names.

9

There's no harm in it, in fact it is often useful to fill in some colours without doodling around with RGB values. It's just that the names might not correspond to the colours that you might expect.

10

const values in that context don't use even a single byte of memory.

11

What do you mean? each colour is 3 non-quantum bytes, you have to put it somewhere

12

The compiler is smart enough to not allocate space for any unused colors. You only pay for what you use.

13

dunno about that, in theory yes, in practice I had to generate my own FFT tables because precalculated tables provided by Arduino library were taking too much memory

14

And, if you only index those arrays with compile-time constants, it might even inline their contents.
