Which Glass Bottle Colour Is Best? Understanding the Benefits of Clear, Amber, Blue and Green Glass
Choosing the right glass bottle is about more than simply selecting the correct capacity and closure. The colour of a glass bottle can also be an important consideration, particularly when packaging products that may be affected by light.
Clear, amber, blue and green glass bottles are all widely used across industries including cosmetics, essential oils, aromatherapy, fragrances, healthcare and other liquid products. Each colour offers a different appearance and may be suited to different packaging requirements.
In this guide, we look at the differences between the most common glass bottle colours and some of the factors to consider when selecting glass packaging for your product.
Clear Glass Bottles
Clear glass is one of the most versatile choices for product packaging. Its transparent appearance allows the contents of the bottle to be clearly seen, making it particularly useful where product visibility is important.
Clear glass bottles are commonly used for products such as oils, serums, fragrances, cosmetic formulations and other liquid products where the appearance and colour of the contents form part of the overall presentation.
Another advantage of clear glass is its clean and simple appearance. It can provide a professional presentation while also making it easy to see the quantity and appearance of the contents.
However, clear glass provides less protection from light than coloured glass. Where a formulation is sensitive to light, the product manufacturer should consider whether an alternative bottle colour would be more appropriate.
Rapid Labs supplies a range of 50ml clear glass dropper bottles and 5ml clear glass dropper bottles with DIN18 necks.
Amber Glass Bottles
Amber glass bottles are a popular choice for products where reducing exposure to light is an important consideration.
The amber colour can provide greater protection from certain wavelengths of light compared with clear glass. This makes amber glass a commonly selected packaging option for products such as essential oils, aromatherapy preparations and other light-sensitive formulations.
Amber glass also has a distinctive traditional appearance and is widely recognised as a practical choice for products where light protection is considered during packaging selection.
It is important to remember that the suitability of any packaging depends on the individual formulation. Product manufacturers should carry out their own compatibility and stability testing to establish whether the selected packaging provides the required level of protection.

Blue Glass Bottles
Blue glass bottles offer a distinctive alternative to clear and amber glass. They can provide products with a premium or specialist appearance while retaining the advantages associated with glass packaging.
Blue bottles are commonly considered for products such as essential oils, fragrances, cosmetic products and other formulations where presentation is an important part of the packaging choice.
As with other coloured glass, the precise level of light protection provided depends on the glass itself, including its colour and thickness. Manufacturers should therefore assess the packaging against the requirements of their particular formulation rather than assuming that all coloured glass provides the same level of protection.
Rapid Labs supplies 50ml blue glass dropper bottles and 5ml blue glass dropper bottles.
Green Glass Bottles
Green glass bottles provide another established option for coloured glass packaging. Green glass has a distinctive appearance and can be used where a traditional or natural-looking presentation is desirable.
Green glass bottles can be suitable for a wide range of applications, including oils, cosmetic products, aromatherapy products and other liquid formulations.
As with blue glass, the level of protection against light depends on the specific glass and the product requirements. If light sensitivity is a concern, manufacturers should assess the selected packaging as part of their product development and stability testing.
Rapid Labs supplies 50ml green glass dropper bottles, as well as other glass bottle formats and sizes.
Clear vs Amber vs Blue vs Green Glass
| Glass colour | Key benefit | Typical consideration |
|---|---|---|
| Clear | Excellent product visibility | Less protection from light |
| Amber | Useful where reducing light exposure is important | Less visibility of the product contents |
| Blue | Distinctive and premium appearance | Light protection depends on the specific glass |
| Green | Distinctive, traditional appearance | Light protection depends on the specific glass |
Which Glass Bottle Colour Should You Choose?
There is no single glass bottle colour that is right for every product. The best choice depends on several factors, including:
- The sensitivity of the formulation to light
- Whether the contents need to be visible
- The desired appearance of the finished product
- The type of product being packaged
- Compatibility between the formulation and the packaging
- The required bottle capacity and closure
- Any product-specific stability or packaging requirements
For products where visibility is important, clear glass can be an excellent choice. Where reducing exposure to light is an important consideration, amber glass is often considered. Blue and green glass provide additional options where product presentation and bottle appearance are important factors.
Choosing the Right Closure
The bottle is only one part of the packaging system. The closure, pipette, dropper or applicator should also be considered when selecting packaging for a formulation.
For DIN18 bottles, Rapid Labs supplies a range of compatible options including bamboo dropper pipette assemblies, rollerball closures and aluminium caps.
Different closure materials and designs can affect the suitability of the finished packaging system, so compatibility testing should be carried out using the intended formulation and complete packaging assembly.
Glass Bottle Compatibility and Product Testing
Although glass is widely used for cosmetic, fragrance, essential oil and other liquid products, packaging suitability should always be assessed for the individual formulation.
Rapid Labs supplies glass bottles and closures for a wide range of applications, but we recommend that customers carry out their own compatibility, stability and suitability testing based on their specific formulation and intended use.
Where available, samples can be requested to allow customers to assess the packaging before placing larger orders.
