Suggested Image Specifications
File Format
The preferable image format is SVG, since it is a scalable vector format, specifically designed for the internet. It is particularly useful for cellular processes since these tend to be diagramatic in nature. It also lends to easier editing, if we decide to change aspects of the scheme. Raster image formats are also acceptable, however one must remember that image quality tends to diminish with scaling. When using a raster format, PNG is preferable to JPEG.

Color Scheme
In order to maintain a standard for Cell and molecular biology articles a standard color scheme should be used. The accepted colors for cellular locations are described in the table. Colors for other components, such as molecules, can be chosen at the discretion of the designer, however, the following should be considered:
- Colors should be chosen so that they contrast with existing colors in the image
- Colors should be chosen such that text can be easily read on it.
- Text should be black
- Arrows should be black, however, different colors may be used to describe a set of processes or to contrast colors.

Membranes
The level of detail for a membrane should be only what is necessary to describe the cellular process.
| Level of detail |
Description |
Example |
Uses |
| High detail |
Shows lipid layers, molecules (head and tail) |
 |
Transmembrane proteins, Fluid mosaic model |
| Medium Detail |
Differentiates between lipid bilayers and single layers |
 |
General cellular process. Molecular interactions. |
| Low detail |
Does not discriminate between multiple membranes. |
 |
Process such as Mitosis, Meiosis. Basic cell structure |
