Roses come in a wide variety of colours, from the classic red rose to less common shades like blue and green. The colour of a rose is determined by pigmentation in the petals. Roses contain colour pigments called anthocyanins that produce the various colours. The most common rose colours include red, pink, yellow, white, and orange, but through selective breeding and other techniques, roses can come in many other colour variations as well. In this article, we will explore the full range of rose colour options available.
Common Rose Colours
Red Roses
Red roses are undoubtedly the most popular and universally recognised rose colour. Red roses represent love, romance, and affection. The red colour comes from anthocyanin pigments in the rose petals. Typically, the deeper and richer the red colour, the higher the anthocyanin concentration. Red roses range from bright crimson to deep burgundy in colour. They make classic gifts for Valentine’s Day, anniversaries, and expressing romantic feelings.
Pink Roses
Pink roses also get their colour from anthocyanins, but at lower concentrations than red roses, giving them a softer pink hue. Pink roses symbolise sweetness, admiration, grace, and joy. They can expressing romantic feelings like red roses, but are sometimes seen as less intense. Paler pink roses are used to express platonic affection, sympathy, and gentleness. Both vibrant and soft pink roses make lovely gifts.
White Roses
White roses contain no anthocyanin pigments, giving them their pure white colour. They represent innocence, purity, secrecy, reverence, and humility. White roses are used in weddings to symbolise new beginnings. They can express remembrance and pay respect to someone who has passed. White roses make elegant floral arrangements and pair nicely with other colours.
Yellow Roses
Yellow roses get their bright colour from carotenoid pigments present in the petals. They represent friendship, joy, delight, and warmth. Yellow roses express happiness and celebration for things like birthdays, anniversaries, graduations, and welcoming new babies. They convey affection for friends and family without romantic implication. Yellow roses brighten up any environment.
Orange Roses
Orange roses contain moderate levels of anthocyanins alongside carotenoids, mixing red and yellow pigments to produce their vibrant orange tones. Orange roses symbolise passion, boldness, enthusiasm, and desire. They convey romance and attraction, but with a playful flair. Orange roses can express your fiery excitement for someone special. The warm colour adds energy to any floral gift or arrangement.
Less Common Rose Colours
Thanks to selective breeding, more rare and exotic rose colours have been cultivated over the years. Here are some of the less common rose colours you may be able to find:
Blue Roses
True blue roses do not exist naturally, but they have been developed using genetic modification and other techniques to produce roses in shades of blue and violet. Blue roses represent fantasy, uniqueness, and the impossible or unattainable. They make stunning, distinctive floral gifts for very special occasions.
Black Roses
Black roses are another very rare and exotic colour. They are not truly black, but extremely dark red, purple or maroon appearing black under certain lighting. Black roses symbolize death, farewell and rebirth. They are frequently used for memorials and somber occasions. Black roses have an air of mystery and elegance.
Green Roses
Green roses are grown using dyes or floral spray paints to achieve their verdant colour since green is not a natural rose pigment. Green can represent renewal, growth, good health, prosperity, and the environment. Green roses make excellent gifts for gardeners and green thumbs. Their unusual colour is sure to intrigue.
Lavender Roses
Lavender roses get their soft purple-grey hue from mixing red and blue pigments together. They symbolize charm, uniqueness, and love at first sight. The muted lavender colour conveys an air of romance and elegance perfect for weddings or anniversary gifts. These roses stand out from the crowd.
Peach Roses
Peach roses get a delicate orangey-pink hue from reduced anthocyanin and carotenoid concentrations. Their soft colour represents appreciation, gratitude, sincerity, and modesty. Peach roses make excellent gifts to convey heartfelt thanks or express your genuine affection for someone special.

Factors Affecting Rose Colour
Several key factors influence the final colour that develops in a rose bloom:
Rose Genetics
Genetics play the biggest role in rose colour. Each rose variety has been selectively bred to produce certain pigments and colour tones. Red roses are bred to maximize anthocyanin concentration, while yellow roses produce lots of carotenoids. Genetics determine the base colour.
Soil Composition
The mineral content in the soil affects the roses’ production of pigments. Iron, aluminum, and magnesium in the soil help roses synthesize anthocyanins for deeper red hues. Phosphorus deficiencies can cause paler yellow roses. Ensuring optimal soil nutrition will maximize colour.
Sunlight Exposure
The amount of sunlight a rose bush receives impacts colour intensity. Brighter sun exposure results in higher anthocyanin and carotenoid concentrations, creating richer reds, vivid yellows, and bolder orange tones. Insufficient sunlight causes colours to fade and look washed out.
Growing Conditions
Factors like temperature, watering, and humidity levels also affect pigment synthesis and colour saturation. Cooler temperatures enhance anthocyanin production for darker reds. Dry spells or insufficient watering can cause paler washed out colours. Optimal growing conditions ensure the truest, most vivid colours.
Harvesting Stage
Rose colour may change slightly depending on harvest stage. Buds tend to appear brighter and more saturated. As roses open fully, colours soften and lighten somewhat. Age and wilting will fade colours further. Peak colour typically occurs with roses at half-bloom stage.
Conclusion
Roses come in an array of beautiful colours, ranging from popular red, pink, white, and yellow hues to rarer lavender, blue, black, and green varieties. The distinctive colour of each rose comes from specialized pigments produced in the flower petals that give red, pink, orange, yellow, or purple tones. Many factors like genetics, soil, sunlight, climate, and harvest timing all influence the final colour that develops. With roses, the possibilities are endless when it comes to finding the perfect colour to express your message or complement your floral designs. Whether you desire classic red roses for romance, cheerful yellow blooms for friendship, or unique blue roses for an air of unattainability, you’re sure to find the ideal rose colour to suit any occasion or mood.
