Is a dahlia red?

To dye clothes and other stuff

If you are using paint then you would just get a big blob of red paint. Or if you are using pencil crayons then it would just look like red. It would look like a solid colour. Or if you are using...

Two, two, two. Or 22 times 102 ohms, or 2200 ohms, or 2.2K ohms, or just 2.2K, as in, "I've got a 2.2K resistor that needs replacing. It's a quarter watt."

An object is red because it is absorbing the blue end of the visible spectrum (higher frequencies) and reflecting back the red (lower frequencies) to your eyes.

Yes red is red but so is period?? soo if red is red then is blue yellow just like craig denhams red pancake? :)
