Forget ph. Take iron nails, copper and zinc or aluminum and place it on 3 sides of the plant near the outside drip line. You will get three different colored blooms on one plant.
The National Arboretum suggests that you can vary the pH to change the availability of aluminum in the soil.
Flower color in H. macrophylla is dependent on cultivar and aluminum availability. Aluminum is necessary to produce the blue pigment for which bigleaf hydrangea is noted. Most garden soils have adequate aluminum, but the aluminum will not be available to the plant if the soil pH is high. For most bigleaf hydrangea cultivars, blue flowers will be produced in acidic soil (pH 5.5 and lower), whereas neutral to alkaline soils (pH 6.5 and higher) will usually produce pink flowers. Between pH 5.5 and pH 6.5, the flowers will be purple (see image at left) or a mixture of blue and pink flowers will be found on the same plant.
Acidic soil turns Hydrangeas blue and basic soil turns hydrangeas pink
Not that I've heard. Many hydrangea strains will have different flower colors, depending on the aluminum content of the soil. When there is available aluminum, the flowers will be blue. When there is no available aluminum, they'll be pink. This doesn't work for white hydrangeas. You can add aluminum sulfate, which is available at most garden centers, to turn pink flowers blue. In order to turn blue flowers pink, raise the soil pH by adding a liming material, and the aluminum will form insoluble compounds and no longer be available to the plants.
ammonia can change the soils pH (acidity level) which can affect the formation of plant pigments or the absorption of elements
The color of terra cotta is a brown-orange combination. Think of a clay flower pot that you would see at a garden center. These are usually terra cotta.
Rocks can be made of assemblages of different minerals whose crystals may be of varying size. This variation in composition and grain size results in a plethora of rock types of different density, color, texture and fabric.
Environmental variation is a change that occurs in your, or anyone's, appearance caused by the environment. Examples are: skin color (like having a tan), a scar, the ability to play an instrument, ability to speak different languages, etc...
Discontinuous
no, as a flower is either for example blue or white, and cannot be something in between, thus its discontinuous variation.
if it changes color because of the pH levels in the soil- red or pink -acidious soil purple-ish -neutral soil blue-basic soil
Go to the following web site. I think it will contain all the information you are looking for. http:/www.hydrangeashydrangeas.com/colorchange.html
Color variation is the difference in colors. For example, a car can come in several colors, this is color variation
You can inherit height, hair color, and eye color.

South Dakota's state flower is the Pasque flower.
Plant height, shape, size and number of leaves, flower color, fruit shape & size etc.
the color of the flower of course! xD
Blue florettes is one name for small blue flowers.Specifically, a florette is a small flower. The color blue may be specified as bright, dark, intense, light, navy, royal or sky-colored. Other terms such as azure, cerulean and cyan number among the terms which designate the range from light to dark to bright which are possible within the color blue.
