$a The effect of the temperature of saturated water steam on the colour change of wood Acer Pseudoplatanus L. $f Ladislav Dzurenda, Michal Dudiak 215 $c Graf., obr., tab. 320 $a Lit. 330 $a The colour change of the wood of tree species Acer pseudoplatanus L.resulting from the process of thermal treatment with saturated water steam at the temperatures of tI= 105 ± 2.5 °C, tII= 115 ± 2.5 °C, tIII= 125 ± 2.5 °C, tIV= 135 ± 2.5 °Cfor τ= 7 hours are presented in the paper. The white to pale white-yellow color of native maple wood varies from pale brown to pinkish-yellow to brownish-red, depending on the temperature of the saturated water steam. In the CIE L*a*b*color space, the changes shown are at the L*- coordinate within the range of L*= 86.0 -65.3 and the chromatic coordinates: red a*= 5.9 -10.8 and yellow b*= 16.4 -19.4.The effect of the temperature of saturated water steam on the variation of the lightness L *, red a * and yellow colour b * of maple wood in the colour space CIE L* a* b* is given in the equation: L*= –0.489∙t+ 132.86; a*= 0.081∙t+ 0.105; b*= 0.059∙t+ 11.445. Significant colour changes of maple wood are observed as a result of technological process at the temperatures above 122 °C. Irreversible changes in colour of the maple wood resulting from one of the modes of colour modification of wood with saturated water steam extend the possibilities of its use in the field of construction-joinery, construction-art and design. 463 -1
