# Object properties – position, rotation, scale, size, brightness, transparency, color.
**Position, Rotation and Scale.**\
These fields exist for all objects. By default the properties **"Position"** and **"Rotation"** are set to 0 0 0. **"Scale"** has values 1 1 1 and equals the size of the QR code.\
\
**There are three ways to change the field values:** \
1\. Hover over the field with the value, hold the left mouse button or touchpad and move the cursor left/right (the fastest way).\
2\. Click the arrows next to the numbers (the smallest possible and precise change).\
3\. Enter a specific value by changing the number in the corresponding field (a quick and precise option if you know the value you need to change).
By changing the values in the **Position**section, we move the object in space along the three axes x y z (left/right; up/down; closer/farther).
Rotation **settings** change the tilt angle in the three planes (x, y, z).
**Scale**, accordingly, scales the object and all objects nested within it.\
Flat objects can be scaled along two planes. To mirror an object, you need to set negative values.\
\
Changing the size in the **"Size"** property does not affect child (nested) objects.
**Color.**\
The color picker dialog depends on the browser and operating system, so your color controls may look different.\
\
The logic of changing color for different object types is similar, but there are nuances.\
\
**Video and image are colored the same way.**\
Pixels that are darker compared to the blended color are replaced (multiplied by the image colors and alter it), while pixels that are lighter compared to the blended color remain unchanged. The color information in each channel is considered, and the resulting color is chosen as either the base or blended color depending on which is lighter.\
Thus, white does not recolor the object (leaves it in its original color), black fully recolors it.\
\
**3D model.** \
To show the color window you need to check the "Paint" box.\
To change the color of a model created in Blender, you must include !primary in the material name (for example !primary-white). That is, all materials starting with !primary will be painted with one color. Other materials will not be colored.\
\&#xNAN;*We will improve this soon.*
**Brightness is adjustable only for the model (from**0 to 100).\
Lightens or darkens the model.
**Transparency is adjustable for primitives, background, images, video and models.** \
**Creates a hologram effect.**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.artar.es/project-creation/object-properties-position-rotation-scale-size-brightness-transparency-color..md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
