Midi-Toulouse
The Stap has made a palette of materials and colors of the department. The setting up of this palette is based on a work of analysis and identification carried out throughout the department, sector by sector, with an interest in old buildings, both rural and urban. The materials and colours were selected from an existing architectural sample characteristic of the sector, so that they can give an indication of composition and colour depending on the structure concerned.
The use of certain references (followed by •) may be limited to special cases: an isolated building or one with a specific architectural character. The other shades have a wider field of use.
In all cases, the choice of shades must take into account:
- the location of the building or house and its natural or built environment.
- the architectural character of the building.
Moreover, since this palette is not exhaustive, it is not impossible to offer a shade outside the palette.
Using the Hue Palette
The shades of this palette are available to meet any request regarding the choice of colours for carpentry and ironwork, whether it is a new construction or the restoration of an existing building. These depend on the colour of the masonry as it is necessary to seek overall harmony.
The range of colours to be used for carpentry and ironwork must be chosen on a single line, with shades from the lightest to the darkest. The colour references come from a universal colour grading system: the Natural Color System (NCS), one of the most widespread and applied systems in the world. Based on how the human being perceives colors, it allows them to give a precise notation based on yellow (Y), green (G), blue (B) and red (R). The reference expresses the clarity of the color (from 10 for the light to 90 for the dark), its saturation (from 10 to 70 depending on the degree) and its tone (composition of the shade). For example, reference 1020 G30Y indicates that it is a green (G) with 30% yellow (Y) very clear (10) and minimally saturated (20). In the palette, shades are classified in an increasing order of clarity and saturation within each tone or color range.
Source of materials
Some slates and stones come directly from quarries in the Pyrenees, while others are recovered materials. Ready-to-use tiles and coatings are marketed products. Lime coatings and coatings are composed exclusively of lime, sand and natural earth colours. These are traditional coatings that are particularly suitable for old buildings, while ready-to-use products are more suitable for new buildings.
Manufacture of lime products
The lime used in the composition of coatings and coatings for the old frame is a natural, aerial or hydraulic lime, and is in no case cement-based. Mixed with dye sands, it is used to make coatings. It is necessary to add earth colours in certain proportions to obtain paints with more sustained tints.
The implementation of all these lime products is traditional masonry.
Shade Details
The traditional slates, if they have a homogeneous tint, take with time and according to their origin a patina more red, more ochre or more blue. This explains the variety of colours of the Pyrenean roofs. On the other hand, the stones have a clean tint as soon as they are extracted, which does not exclude that they also patinate over the years. With regard to lime materials, these are products that have to evolve naturally, dyeing according to light and the environment, which gives them a certain visual richness.
