The two colors I find the hardest to get “right” are red and white. Red because the subtle variations in the color can be difficult to see and it changes depending on the light — especially between natural and artificial lighting. White is difficult because it looks blue, gray, or even dark red — again depending on light, but also on shadows, time of year, hour of the day, and whether it’s sunny or overcast.
The sun changes color. It’s amber in the autumn — most amber in mid-October, at least in this part of the country. It’s the world best light for color portraits and for dark skinned people, that color of sunshine makes them glow in a beautiful way. Winter sunlight has a blue tinge and has a hint of red in summertime.
We don’t usually get spring around here, so who knows? I think it’s a bit yellow, but spring in New England last about two hours between late morning and the end of lunch — and then, it’s summer.
All the different colors are considered white — but white isn’t really a color. It’s “all colors.” In theory, if you mix all the “basic” colors together in equal quantities, they would become true white, but of course, that never happens. You mix them and you get muddy brown or sort of gray or putrid greenish brown. Pure color is not the same as the colors on your color pallet.
I remember as a kid, after reading about colors, trying to create “real” white and “real” black. You can’t — at least not at home with your paints. In our reality, there is no true black. Maybe in deep space it’s true black. Black clothing — unless it was all dyed in the same batch using the same dye — won’t match. It may look gray or dark (very dark) navy blue, but it is never true black. It can be infuriating to try to match black with black only to realize while both are “black,” they aren’t the same color — or even close. I usually solve the problem by mixing black with denim or some shade of gray — or anything really — as long as it matches my earrings.
In theory, black is the complete absence of color while white is all colors. It’s just something to think about, even if it never applies reality.
