The possibility of using color system CILAB that is present within Photoshop in quantification wood or phenotypic patterns of populus euphratica wood. This technique also enabled the clarification of color quantitative changes on the level of steric axes for each color factors (L, A, B) -lumber moisture ,at the moment of measurement, played an important role in quantitative changes of color factors and revealed clearly the presence of significant differences between these color components, particularly with respect to transparency degree and this in turn affected naturally on both color axes A, B . this work Also showed the role of some independent factors taken from color differences, in which the phenotypic factor comes in the forefront of the trunk and the height level and the maturity degree or the year of lumber formation and the nature of lumber formed (barky wood and core wood) since these factors are taken either individually or combined they have an incorporeal role and influence on color quantitative changes of wood according to the taken Physical situation.-This study enabled uncovering the presence of the color range on the phenotypic pattern level. This color range of the studied color factors is of course a direct contrast of the measured color values via CILAB system and it paved the way to detect the presence of color thresholds and clarifying gradient color values measured both at the phenotypic pattern level of the trunk or at the level ofthe radial direction or at the level of the sample height. -different analyzes showed the possibility of detecting the tensile wood by using color technique CILAB through the concept of color differentiation on the studied wood section and as is evident from the previous analyzes, the most significant color factor in that lies in L values (the transparency degree of the section) and the lesser significant color factor b that reflects the color gradient between yellow and blue, and this result has been a prelude through some physical tests that indicated the 001 presence of tensile wood especially the axial shrinkage and relative density. On the other hand, the trunk model (phenotypic style) has an important role in changing color components, as well as height levels through various tests previously mentioned. Recommendations: 1. Do a dissection study of the wood sections in areas of color differentiation to deepen the concept of tensile wood existence. 2. Do biochemical analyzes to be sure of the nature of the wood formed in the areas of color differentiation. 3. Study the geometric cross sections in order to connect them with the color differentiation areas and to clarify their impact on tensile wood formation. 4. Applying this methodology to other forest types in order to deepen the concept of color as a descriptive and quantitative indicator on the presence of tensile wood
