3.03 Colours on screen

General colour use in TactileView

Green Green

The colour green is used as a colour for information. Everything you see in this colour is NOT printed on the design. Examples are: the font ‘beneath’ the braille dots of the textlabels, the alignment lines for the text labels, the grid for aligning object in the drawing area, the letters at the angles for the triangle.

Blue Blue

Objects created with one of the drawing tools (square, line, circle, dot, etc.) are presented in blue. Variations of blue are used to indicated the selected dot height (for embossers that support varying dot heights). A lighter blue colour indicates a lower dot height.

Black Black

Lines that are created with the drawing tool ‘Retouching: Adding lines’, are drawn in black. This indicates that the line is part of the underlying bitmap in the design. The bitmap consists of individual pixels that can be erased by choosing ‘Retouching: Erase’.

Any colours present in images inserted from file or from the internet will be converted to braille dots. These images should be processed using the filters and be converted to black/white in order to print them in braille lines.

Purple Purple

Markers are placed on or around a selected object. These markers can be used to reposition or resize the object, or change its proportions. Markers with a different function will have a different colour instead of purple.

Red Red

A red border is surrounding the drawing area, reflecting the printable area of a sheet of paper in the selected paper size. When the designs exceeds this initial area, the red borders will signify that multiple sheets of paper will be printed that together will contain the design.

Special cases

Text labels

A rounded marker precedes each text label to signify the type of input used for the specific label.

  • Green text label bullet Green is used for text labels entered with the regular computer keyboard;
  • Orange text label bullet Orange for those that were created with Perkins style input;
  • Blue-grey text label bullet Grey/blue for mathematical textlabels, created with the MathType equation editor.

Formulas in graphs

When multiple formulas are used in a graph, each formula in a graph will have its own colour (red, green, blue and yellow) to easily distinguish between them. These different colours are only used for display on the screen and will not lead to differences on a print.

Different colours distinguish the formulas of a graph

Braille tables
In a single document, multiple braille tables can be used to accommodate for language variations. In the design toolbar (right vertical toolbar when nothing is selected), click ‘Show used braille tables’ to see an overview of the different braille tables in the design. Colours are used in the legend and design to distinguish the different braille tables.

Audio styles

Objects with audiostyles are presented with a light red/pink fill.

Circle with an audio style
