We study the colors and orientations of structures in low and intermediateinclination barred galaxies. We test the hypothesis that barlenses, roundishcentral components embedded in bars, could form a part of the bar in a similarmanner to boxy/peanut bulges in the edge-on view. A sample of 79 barlensgalaxies was selected from the S$^4$G and the NIRS0S surveys. The sizes,ellipticities, and orientations of barlenses were measured and used to definethe barlens regions in the color measurements. The orientations of barlenseswere studied with respect to those of the "thin bars" and the line-of-nodes ofthe disks. For 47 galaxies color maps were constructed using the SDSS images infive optical bands, u, g, r, i, and z. Colors of bars, barlenses, disks, andcentral regions of the galaxies were measured using two different approachesand color-color diagrams sensitive to metallicity, stellar surface gravity, andshort lived stars were constructed. Color differences between the structurecomponents were calculated for each individual galaxy, and presented inhistogram form. We find that the colors of barlenses are very similar to thoseof the surrounding bars, indicating that most probably they form part of thebar. We also find that barlenses have orientations closer to the diskline-of-nodes than to the thin bars, which is consistent with the idea thatthey are vertically thick, in a similar manner as the boxy/peanut structures inmore inclined galaxies. Typically, the colors of barlenses are similar to thoseof normal E/S0 galaxies. Galaxy by galaxy studies show that in spiral galaxiesvery dusty barlenses also exist, along with barlenses with rejuvenated stellarpopulations. The central regions of galaxies are found to be on average redderthan bars or barlenses, although galaxies with bluer central peaks also exist.
