Основываясь на этом задокументированном ответе и этом ответе, учитывающем алгоритмы , я попробовал простой интерфейс для смешивания цветов с использованием аддитивного и субстративного подхода.
Вы должны подтвердитьчто первичные цвета RGB и CMYK дают вам вторичные цвета на первых диаграммах ответов:
- Красный + синий = пурпурный (на добавке)
- Желтый + голубой = зеленый (на субстративном)
- и т. Д. ...

В основном, эти операции аналогичны логическому И и логическому ИЛИ.(Ну, не совсем)
- На аддитивном алгоритме цвета перекрываются, но для каждого основного он может быть только 255 (логическая операция ИЛИ)
- На субстративном алгоритме, если какой-то основнойотсутствует, результат не будет иметь (CYAN не имеет КРАСНЫЙ, ЖЕЛТЫЙ не имеет СИНИЙ: вы получаете ЗЕЛЕНЫЙ) (Логика И Операция)
На основе это , которое вы можете получитьтретичные цвета из сочетания первичных и вторичных цветов, поэтому я делаю крошечную реализацию, которая работает довольно хорошо:
NewColor.R = Color1.R - (Color1.R - Color2.R)/2
NewColor.G = Color1.G - (Color1.G - Color2.G)/2
NewColor.B = Color1.B - (Color1.B - Color2.B)/2
Существует также разбавляющий / субстративный алгоритм, упомянутый во втором цитируемом ответе, но я не могу сказать, что этооснован на, только что добавлен в тест.
