The color range of roses is remarkable. The only colors missing in roses are true blue and black. And now with
the help of genetic engineering, the true blue rose and perhaps even the black rose ( some deep red roses verge on
being black) are not far off.
When considering rose flower colors, it helps to know that most, old roses come in cool or pale colors, such as pale pink, soft pink lilac, or faded yellow.
Modern roses, however, come in bright or warm colors, such as vivid yellow, red, orange, gold or pure white.
When planning your colors, it's important to know that not all rose bloom colors are stable.
Growing conditions as well as the number of pigments affect colors. Soil fertility, temperatures, the heat of the sun, and rainfall, all play roles in determining the colors of some roses.
